What to Bring to the SAT and What Not to Bring SAT / ACT Prep Online Guides and Tips After months of planning and prepping, test day is finally upon you! What exactly do you need to bring to the SAT- and what should you just leave home? We’ll talk about what to bring to the SAT for certain and some not so obvious things that might come in handy. Make sure your bag is packed and ready to go so you can focus on performing your best- and not on tracking down a pencil sharpener! What to Bring on SAT Day: The 4 Essentials First things first: what must you bring to the SAT? Here are the four essentials you cannot afford to forget on test day: #1: Admission Ticket You must print out your admission ticket and bring it to the testing center. A paper copy of your ticket is 100% necessary for admission- you can't show it on your cell phone, tablet, etc. To print it out, log into your College Board account and click on "Print Admission Ticket." #2: Photo ID Your photo ID should resemble the picture you uploaded to the College Board website when you registered for the SAT. Below is a list of acceptable and unacceptable forms of ID: Unexpired government-issued IDs (e.g., driver’s license, passport, military ID, national ID, etc.) Current school ID card Student ID Form, if you don’t have any of the other forms; this form must be prepared by the school you currently attend or by a notary if you are home-schooled Unacceptable IDs include IDs that are expired or damaged or do not match your College Board photo. Some unacceptable forms of ID include the following: Credit or debit cards (even ones with photographs) Birth certificates Social Security cards Employee ID cards ChildFind ID cards Other temporary ID cards #3: At Least Two #2 Pencils and an Eraser Pens, highlighters, liquid paper, or any other writing utensils are not allowed,not even for the essay (if you're taking the SAT with Essay). Check your erasers to make sure they work well. #4: An Acceptable Calculator You'll need to bring your own calculator for the Math Calculator section. Acceptable calculators include graphing and scientific calculators. A basic four-function calculator is also allowed but not recommended. Learn all about the uses and limitations of your calculatorwith our guide. Unacceptable calculators and devices include the following: Laptops Tablets Cell phones Calculators that make noise or use a keyboard-like (QWERTY) keypad, an electrical outlet, or a paper tape Basically, don’t bring anything that could be disruptive or has communication capabilities. As long as you have these four items- your admission ticket, your ID, pencils/erasers, and an approved calculator- you should have no trouble being admitted into the SAT. Now that you know things to bring to the SAT, let’s consider a few other materials that might help you out during the test. Other Items You Might Want to Bring to the SAT In addition to the four essentials, what other items can you bring to the SAT? Here are some of our recommendations for things that might come in handy on SAT test day: Extra #2 pencils and a small handheld pencil sharpener. Since time is tight and talking is prohibited, you definitely don’t want to find yourself in the middle of the SAT with nothing to write with! So bring some backup writing utensils and a sharpener. Extra batteries for your calculator, just in case. It’s also a good idea to put in new batteries the day or two before the SAT- and definitely make sure that your calculator works! A drink and snacks for your breaks. These will likely have to stay in your bag, in a locker, or up at the test administrator’s desk and will have to be consumed outside of the testing room. The SAT is a long test; drinks and snacks will help you stay hydrated, energized, and focused. A watch,as long as it doesn’t have any audible alarms or noises. If it'll help you keep track of time, bring one along. If you just find it distracting, though, leave it at home! These extras and backup materials might prove helpful the day of the SAT. Now, whatshould you definitely not bring on SAT test day? What NOT to Bring to the SAT There are lots of prohibited items when it comes to SAT test day. We’ll list a few below, butyour best bet is to avoid bringing anything that’s not recommended on the above lists: Any other technology besides your calculator, especially anything with communication or recording capabilities. This means no cell phones, laptops, tablets, timers, cameras, or audio recorders. The College Board takes security very seriously, as you can tell from these high-profile cheating scandals. Any other notes,cheat sheets, dictionaries, translators, books, or papers. To reiterate, if you must bring your cell phone, turn it off well before the test. If it beeps even just once, your proctor will confiscate it and cancel your test immediately. Want to learn more about the SAT but tired of reading blog articles?

Getting Ready for SAT Test Day: 5 Key Tips Now that you know exactly what to bring (and not bring) to the SAT, how can you ensure that you are prepared to do your best on the test? Read on to learn how you can have a great SAT test day: #1: Prepare Ahead of Time Get all your materials gathered and packed the day before your test. You definitely don’t want to be scrambling in the morning trying to track down pencils and batteries for your calculator. This would cause a whole lot of unnecessary anxiety and could make you late (and therefore ineligible) for the test! So get everything taken care of at least the day before. #2: Test Your Calculator Before the SAT, check that your calculator is working properly. Test out the different functions, and put new batteries in it so that it won't have any chance of dying during the test! #3: Print Out Multiple Copies of Your Admission Ticket It's a good idea to print out a few copies of your SAT admission ticket, just in case. If you don’t have a printer, you can get this taken care of at school, your local library, or another printing center such as Staples. Remember that you will not be admitted on test day without this ticket. As mentioned above,don’t wait until the morning of or late the night before the SAT to print out your ticket. It’s a strange and inexplicable rule of printers that they tend to malfunction right before a big test or due date. So print out two or three copies early and save yourself the hassle! #4: Practice Self-Care Self-care is important in general but especially in the days leading up to the SAT. The morning of the test, eat a healthy breakfast. Exercising the day before (and in general) might also aid in easing your stress levels and clearing your mind. Don’t underestimate the power of diet and exercise in feeling good and thinking clearly! #5: Double-Check That You've Got Everything You Need Finally, make a checklist and double-check your bag one last time before you head to your testing center.

Elements of the Legal System Essay Example | Topics and Well Written Essays - 1250 words

Elements of the Legal System - Essay Example The adversarial type is always seen on films and read in novels. The adversarial model works in two types of criminal cases: First are the celebrated cases, where famous people are involved, or cases that are horrifying and beyond the normal type of crime. Second are the serious felonies, which include serious misdemeanors that are done by strangers. The consensual model is a model classified as more effective because there is good cooperation from both the defense and prosecutor. In this model, the two attorneys from both sides share the same understanding of the crimes and punishments. These attorneys think that arguing over the case will only slow down the court proceedings of the case when their main purpose is to make the process faster and finish the throng of cases as quickly and effectively as possible. Crime Control vs. Due Process Models. Crime control model is the assurance of public protection. This type of model believes that all criminal suspects are guilty; thus, their cases should be dealt quickly in the courts or in any other legal branches. The legal process of this model with the criminal suspects is characterized like that of a conveyer belt where all cases and the suspects pass by in the conveyer belt quick and fast. â€Å"Crime control and consensual models complement each other since crime control gives importance to quickly and efficiently convict criminal suspects to ensure the public their safety† (Barkan, 2009). The consensual model gives importance of the same goal but only because to ensure of the continuous and uninterrupted court proceedings. In contrast, due process model is a model that protects and ensures the suspected criminal from the likely abuse of the government of its power. This model take into consideration that the suspected criminal or defendant is innocent of the charges thrown at him. In a democratic country, both the innocent and the guilty deserve to have proper court proceedings and ensure of their indivi dual freedom. The adversarial model and the due process model â€Å"complement each other† since the former model stresses on challenging the evidences of the two parties while the latter highlights on protecting the rights of the suspected offender (Barkan, 2009). Lawyers The significance of the function of a defense attorney is to talk and act in behalf of the defendant. A defense attorney understands the fair process of the criminal justice system. A defendant is in need of every legal advice and counsel throughout the court proceedings, and a defense attorney is the one that gives such. A defense attorney also â€Å"represents the defendant after the he or she is taken into custody†¦to give advice and to make sure constitutional rights are not violated during pretrial procedures† (â€Å"The Adversary Justice System,† n.d.). The prosecuting attorney does not give advices the same way a defense attorney does. A prosecutor’s responsibility is making sure that parties involved in the trial are conscious and be aware of legal measures. Prosecuting vs. Defense Attorney. The prosecuting and the defense attorneys both lay their sides to the judge and to the jury, and during the trial proceedings of the case both are involved. The prosecuting team goes first in presenting evidence that proves the conviction of the defendant followed by the defendant who is going to present his or her

This up-to-date proposed legislation is directed to create an abbreviated pathway, as well as the potential effect of the said pathway for FOB approval of the PHS Act biologics on specific federal spending. In recent years, the introduction of bio-equivalent generics for drugs which are chemically synthesized or "conventional drugs" resulted in considerable generic penetration as well as average price effects (Mathieu, 2004; pp. 10-1). In pharmaceutical industries, Patents serve to protect inventors' intellectual property rights at the same time allowing them to share information which others might use in order to progress or advance the field. Yet, in the modern pharmaceutical business, the system is quite grossly abused as it permits companies to patent drugs which are not reasonably considered as "new inventions'. As a matter of fact, several companies flooded the market with drugs which are not affordable. This practice has been used by many companies to prevent altogether and delay competition among generic drugs. 2008) that those doctors prescribe. Doctors normally prescribe more drugs the moment they acquire gifts from drug makers.

Risk And Adults With Learning Disabilities

Risk And Adults With Learning Disabilities A significantly reduced ability to understand new or complex information, to learn new skills (impaired intelligence), with a reduced ability to cope independently (impaired social functioning); and a condition which started before adulthood, with a lasting effect on development (Scottish Executive, 2010). People with learning disabilities comprise of a highly vulnerable section of the society, who have limited access to health care facilities / services offered to them. They are often faced with obstacles and challenges while copying with grave situations such as loss and bereavement of loved ones, personal illness, death etc (Elliott, 1995). This, in turn, tends to aggravate their situation and increase their dependence on the society which includes their friends, family and loved ones as well as the community in general. They are known to have been ignored persistently in terms of providing services in the need of personal illness, death, and other challenging life situations, thus increasing their vulnerability all the more. Risk vulnerability: People with learning disabilities are one of the most vulnerable groups in the society (Department of Health 2001). People with learning disabilities has probably one of the worst histories is neglect and ill treatment in any group of society. Among the most vulnerable members of society they cant speak up for themselves. Concepts of risk assessment and management in psychiatry increasingly reflect public and professional anxieties that people with a mental disorder may harm others (Simon Halstead (997). At risk are the mens victims whose suffering was often exacerbated by service providers failure to protect them. For example, if consequences are limited when a man with learning disabilities abuses another person with learning disabilities, the victim may be left with the idea that such behaviour is normal and acceptable, and that services will provide little protection and that their complaints will not be heard. It may also increase their vulnerability to further abuse because abuse can become normalised (McCarthy and Thompson, 1996). The oxford dictionary define noun risk as meaning a hazard, a dangerous, exposure to mischance or peril, as verb it also similar which means hazard, to danger, to expose to the chance of injury or loss(P. Parsloe, 2005). Risk is closely linked to dangerousness, resulting in harm which seems to be agreed means harm to self or others and extend of harm which constitutes a risk in various situations especially adult with learning disabilities. If you dont know for sure what will happen, but you know the odd that is risk and if you dont know the odd that is uncertainty (Knight, 1921). From this definition of risk concentrate upon the probabilistic components in knowledge, and is agnostic as to whether this involves probabilities of good of bad outcomes. Royal Society(1983), risk assessment which saw as the probability that a particular adverse event occurs and social services has been concerned predominate with risk assessment to prevent harm. They may also suffer further if they have to deal with seeing their perpetrator on a regular basis, and may be subject to further assaults in retaliation of their initial complaint. It has been noted above how services frequently respond inadequately to the abuse of people with learning disabilities by men with learning disabilities: only rarely will the police be involved and most victims will have no option but to continue to see their attacker on a daily basis (Thompson, 1997). In addition to the risks to existing victims, poor responses may result in increasing numbers of people being abused. Definiation of vulanarable adult in section 80(6) care standard act 2000 states that- (a) an adult to whom accomodation and nursing or personal care are provided in care hom (b) in adult to whom personal care is provided in their own home under arrangements mad by a domiliciary care agency.(Ian. PeateD.Fearns-2006) Adult with learnign disabilities, and thos peopl who have a lescapcity like who have mental illness, old and frail,need protection from potentially abusive sitaution over which they might have little control (Department of Health,2000). Learning Disability Adolescents obviously do not always act in ways that serve their own best interests, even as defined by them. Sometimes their perception of their own risks, even of survival to adulthood, is larger than the reality; in other cases, they underestimate the risks of particular actions or behaviours. It is possible, indeed likely, that some adolescents engage in risky behaviours because of a perception of invulnerability-the current conventional wisdom of adults views of adolescent behaviour. Others, however, take risks because they feel vulnerable to a point approaching hopelessness (Fischhoff et al., 2000). In either case, these perceptions can prompt adults to make poor decisions that can put them at risk and leave them vulnerable t o physical or psychological harm that may have a negative impact on their long-term health and viability. Learning Disabilities: Risk Assessment Decision Making Process/ Practice Tools: Every day a lot of risk situation changes rapidly and what applied yesterday but may not today. Those service users who are identified as at risk would be provided highly effective instruction to reduce their risk in the identified area (e.g., language, reading, numeracy/ math, behaviour). Service users whose response to instruction moved them out of risk status would receive no further supplemental intervention. Service users whose response to well-documented, effective, and well-implemented instruction was low or who remained at risk would be considered for placement in special education. Thus, potentially, many Users could benefit from this type of an identification procedure. (S.Vaughn and Lynn S. Fuchs, 2003). For minimize risk and make it useful and meaningful, may risk situations need to be reassessed regularly perhaps daily basis according service users daily need. People with learning disabilities are subject to risk all time due to their vulnerability they sometimes abused by those who have control over them or by those who realize that they are vulnerable because of their disabilities they often find it very much more difficult to assess risk the way most of us do. While most of carer don dont asses risk very efficiently they generally make some attempt to do so. Its not easy at all to do risk assessment as it is a complex task and most of the time carer or support worker they do adequately but not very thoroughly. Adult with learning disabilities they always find this difficult and also fail to recognize any risk at all as they cant explain due to lack of communication. In spite of some difficulties, there is an increasing awareness that people with learning disabilities can make choices, moreover they want to do so. However its often fail to consider is that, the amount of risk that these choices carry and most of us have grown up accustomed to risk-taking. Life is full risks we all take risk all the time and the more familiar they are the less we tend to recognize the real level of risk involved.(Refe). Many problems about assessing risk that different services user may perceive the different risk. What is acceptable to one person may not be acceptable to another. Main objective of the risk assessment when its possible may sometimes affect decision making in number of different ways. Its true many people with learning disabilities who are always facing risk in their everyday life. Significantly about choice decision sometimes its difficult for adult as well carer to make right choice how could be at risk. The difficulty for people with learning disabilities is that carers often do feel often they are expected to make these choices for them. The law of negligence can appear to inhibit decision making personal freedom and choice sit uncomfortably next to the concepts of duty of care and professional liability (Ref.). people with learning disabilities may not have done perhaps carers need to be encourage to help their service users how to make choices with and appreciation of the risk involved. This is more challenging task than just encouraging choice alone it seems that not only should people with learning be allowed to make choices and take risk they should actively be encourage to do. Multidisciplinary Risk Assessment: The problem with the right to make choices is that it assumes that adult with learning disabilities are able to make choice about risk in the same way every one does(Refe.). we have to acknowledge that adult with learning disabilities do have real difficulties with many cognitive takes. Most we have problems in assessing risk effectively because of the complexity of doing so it is likely that people with learning disabilities will find the particular difficult. The assessment of ability to consent and the ability to make real choice, especially in relation to understanding the likely consequences of the choices or decision made. It could be helpful when any risk assessment pan to do like- If carer want to take any decision about the adult person, Is person are aware that about their decision at all? Are they communicating their choice decision making? Giving people with learning disabilities more choice especially about taking risk, its mean that carer have to be alert to the extent to which the service users are able realistically to assess the level of risks involved(Ref.). In order to decide when risk is acceptable, they need to consider a large number of pieces of information which is decision making become difficult for carer/support worker. Many adult with learning disabled the most successful way to avoid and minimize risk to avoid further problem is by effective management. When the person concerned may have been living in a setting where the opportunities for such behaviour have been very limited or absent, carers and professionals are sometimes tempted to assume that because the recent past has been incident-free the problem has disappeared. Risk Assessment: Never take someone with a learning disability swimming without first reviewing their risk assessment plan. A risk assessment is in place to address issues of importance such as dangers, hazards, and known triggers and how best to avoid them. Make sure you are familiar with the particular risks that you could face with the person in your care and that you have put measures in place to reduce, or eliminate, them. Assessment is a complex and time consuming task and it is a continuous process. Assessment of risk for adult with learning disabilities which should be evolutionary in nature constantly informed and shaped by changes of circumstances upon service users needs (M.Brown, 2003). The practice of risk assessment and management is the process of data collection, recording, interpretation, communication and implementation of risk reduction plan (Maden, 1996). For the risk of learning disability, clinical model of risk assessment have become the norm. There are two kinds of risk that are relevant to work people with learning disabilities, risk of unnecessary exposure to undesirable events or experience, and risk of negative consequences when possible benefits and desirable experiences are perused (Paul William, 2006). Above this it is clear that a strategy of prevention should implement, and management is required so that risk and benefit are balanced. In social care and health care there are broadly two main context of risk which are not provided and everyday risk in their life. people with learning disability to have a history of formally documented offence. Conclusion People with learning disabilities are beginning to reclaim the lives they lost in the institutions, having choices, jobs, sex lives and even becoming parents unthinkable until even quite recently. Slowly, perhaps far too slowly, the rest of the community is beginning to realize that the majority of people with learning disabilities are not so different from everyone else, and need the same things in their lives that all of us do: work, leisure, partners, and a sense of being part of a social group. They want to feel useful and valued, as we all do. Life is full of risks. We all take risks all the time, and the more familiar they are the less we tend to recognize the real level of risk involved. We actually take the greatest risk in our lives every time that we step into a car, but few of us really consider that risk seriously. This is the other side of the coin; we are inclined to believe that it wont happen to me, even when the objective statistics suggest otherwise. The difficulty that now exists for people with learning disabilities, especially those with greater handicaps, and those who care for and support them, is that the law specifies that many such people are vulnerable, and not able to make this choice for themselves. They are considered to be unable to assess the risks involved and thus make an independent choice. The onus of assessing risk and making the decision therefore often rests with carers. Because it is such a difficult decision to make for someone else, carers often take the simple way out, and avoid letting situations arise where learning-disabled people in their care have the opportunity to develop sexual relationships: if a person cannot make an informed choice then perhaps it is easier not to offer them that choice. This is the current dilemma for those who work in community care situations. The issue of sexual relationships is perhaps the most difficult and complex, but this problem of balancing risk and choice is a constant one for carers and professionals, in relation to many aspects of everyday life. In the background is the ogre of the law (and/or local management), ready to jump on the unwary, should they get it wrong. No wonder, perhaps that many are cautious about enabling such choices to be made. Recommendation Social services departments have seen a rise in the numbers of vulnerable adults referred to them because they are at risk of physical and sexual abuse, as well as financial fraud, a study has found. The survey of directors of adult services suggests the fallout from the death of Baby Peter has influenced social workers attitudes to vulnerable adults with more older people or those with a learning disability deemed to be at risk of abuse being referred for assessment. Speaking ahead of the national children and adults conference that opens today in Harrogate, the Local Government Association (LGA) warned that adults services were coming under increasing strain and called for reform of the way adult social services are funded to meet the explosion in demand and escalating costs. In others for example, in the increase in the number of adult safeguarding referrals it might be that the higher profile of risk and vulnerability has led to a greater vigilance by our care staff and by members of the public alike.

robert browning speakers Essay -- essays research papers

West Comparing speakers: My last duchess and porphyria’s lover   Ã‚  Ã‚  Ã‚  Ã‚  The great poet Robert Browning, who created the poems My Last Duchess and Porphyria’s lover, had an interesting taste for speakers of his poems. He seems to be fond of violent, sexual and eccentric people to narrate his intriguing poems. In his poem Porphyira’s Lover, a dramatic monologue, a man in a cottage talks of a woman who brings cheer to his house when she appears out of the storm outside. When the man realizes the moment won’t last, he kills her by strangulation and lays her by his side. In his other poem, The Last Duchess, The Duke of Ferrara is the speaker of the poem, and tells us he is entertaining an emissary who has come to negotiate the Duke's marriage to the daughter of another powerful family. You soon realize when reading the poem that he killed his former wife The Duchess and speaks of her poor behavior despite all of her fortunes. Through out both of these poems Browning’s genius choice in speakers is very prevalent and the similarities and differences between the speakers are striking.   Ã‚  Ã‚  Ã‚  Ã‚  When talking about how these speakers are similar there are many characteristics that the Duke and the man share. First of all, the men both kill the women the love. The duke killed the duchess because she flirted with everyone and did not appreciate her great name. On the other hand the man killed the woman in the cottage because he was afra...

Advantages and Disadvantage of technology

Technology changes and improvements have been applied in all sectors of the economy as well as the arms of the government.   Many employees and employers and the society in general embrace technology in different perspective depending on the impact it will cause on their lives.The police department as many other sector has also been embracing technological changes to be able to deal well with the increasing cases of crimes.   Generally, any technology will either have a positive or negative impact on all stakeholders.The recent technology that the police have continuously used is the use of stun guns and patrol car video surveillance to tackle criminal activities and provide protection to the citizens.Use of the stun guns.Stun guns are weapons that are aimed at disabling a victim temporarily by delivering high voltage electric shock.   There are various means in which the stun gun is used to a victim.   The aim of the stun gun to disable a victim but many people have ended up being killed by the used of guns.Tasers are a type of stun gun now being used by the police in the United States â€Å"[Tasers] are designed to incapacitate by conducting 50,000 volts of electricity into your body.   The electrical pulses induce skeletal muscles spasms that immobilize and incapacitate, causing you to collapse to the ground†, (Indyhack 2007).According to Eliot, more than 150 people have died in the US because of being struck by tasers since January 2001, and 61 in 2005.   Most of the death victims died because of being subjected to multiple or prolonged shock.   The police have been drawing the tasers so quickly even in cases that the use of such extreme force is not necessary.   For instance,Deputies fired Tasers at a teenager who ran after not paying $1 bus fare, a 71 – year who refused to get into a police car, and partially deaf man who could not hear deputies ordering him to stop†¦About three out of four of those shocked by Seattle po lice were unarmed, (Indyhack 2007).Apart form the abuse of the Tasser weapons by the police, the use of the Tasser can have side effect on the victim, in the long run. There is no any scientific proven research done to allay fears about the electrocuting of human beings by use of the gadget.Taser only relies on two studies.   The studies were done by company paid researchers’ on a single pig in 1996, and on 5 dogs in 1999, (Indyhack 2007).   Because of lack of scientific research, health hazards cannot be ruled out.Despite these problems associated with the use of the stun gun police, have vehemently defended the weapon use.   They argue that the weapon can be used rather than police handguns especially on victims who are armed with different weapons other than guns, or on victims who are mentally sick.   In this case, many lives will be saved because of the use of the less lethal weapons.Patrol car video surveillanceMany people because of the fact that it has played a big role in preventing crime have welcomed the video surveillance technology.   This system is one of the technologies that have quite well used to control criminal activities in most cities, homes, business building and public places.It has been widely accepted by many people that the surveillance system has highly reduced the cases of criminal activities, â€Å"Instead of being perceived as an Orwellian intrusion, the cameras in Britain proved to be extremely popular. They were hailed as the people’s technology, a friendly eye in the sky, not Big Brother at all but kindly and watchful uncle or aunt†, (Arroyo, 2002).The problem with using the surveillance is when it is combined with other technologies such as biometric facial recognition, thermal sensing, infrared, and other that greatly enhanced human visual capabilities (Arroyo 2002).If this system is used in line with the audio recording, the system will violate Title 1 of the Electronic Communications Act.   This is because the combination of the surveillance style and audio recording without a person’s knowledge is violating the person’s privacy.   This is especially a big problem if the police use the systems without being controlled, as they infringe on many rights of the people.The other problem that is associated with this system is that it also implicates on peoples free social life.   The monitoring of peoples’ movement in the society implies that a person will not be a free man in his own society, as someone somewhere is watching his movements. This system seems to undermine the people’s way of life as well as compromising it.Therefore, despite the fact that the surveillance might reduce many cases of criminal activities as some people argue, it at the same time causes destruction to the way of living of people and inducing the to conformity as one is not sure whether he is being watched or not.  Those who argue for the use of the surveillance system, they do see that the issue of security has become more important than only the social part of life. Hence arguing for the continued use of the system.ConclusionBoth use of the stun gun and the surveillance machine can be of much beneficial to the society only if they are applied in the correct manner that does not in any way infringe on a person’s rights.   Or else, as much as they are being applied as now, they have left many people’s rights abused.

Why Do Helium Balloons Deflate

Helium balloons deflate after a few days, even though ordinary latex balloons filled with air may hold their shape for weeks. Why do helium balloons lose their gas and their lift so quickly? The answer has to do with the nature of helium and the balloon material. Key Takeaways: Helium Balloons Helium balloons float because helium is less dense than air.Helium balloons deflate because helium atoms are small enough to slip between spaces in the balloon material.Helium balloons are Mylar and not rubber because there is less space between the molecules in Mylar, so the balloon stays inflated longer. Helium Versus Air in Balloons Helium is a noble gas, which means each helium atom has a full valence electron shell. Because helium atoms are stable on their own, they dont form chemical bonds with other atoms. So, helium balloons are filled with lots of tiny helium atoms. Regular balloons are filled with air, which is mostly nitrogen and oxygen. Single nitrogen and oxygen atoms are already much larger and more massive than helium atoms, plus these atoms bond together to form N2 and O2 molecules. Since helium is much less massive than nitrogen and oxygen in the air, helium balloons float. However, the smaller size also explains why helium balloons deflate so quickly. The helium atoms are very tiny — so tiny the random motion of the atoms eventually lets them find their way through the material of the balloon through a process called diffusion. Some helium even finds its way through the knot that ties off the balloon. Neither helium nor air balloons deflate completely. At some point, the pressure of gases on both the inside and outside of the balloon becomes the same and the balloon reaches equilibrium. Gases are still exchanged across the wall of the balloon, but it doesnt shrink any further. Why Helium Balloons Are Foil or Mylar Air slowly diffuses through regular latex balloons, but the gaps between latex molecules are small enough that it takes a long time for enough air to leak out to really matter. If you put helium into a latex balloon, it diffuses out so quickly your balloon would deflate in next to no time. Also, when you inflate a latex balloon, you fill the balloon with gas and put pressure on the inside surface of its material. A 5-inch radius balloon has roughly 1000 pounds of force exerted on its surface! You can inflate a balloon by blowing air into it because the force per unit area of the membrane isnt that much. Its still enough pressure to force helium through the wall of the balloon, much like how water drips through a paper towel. So, helium balloons are thin foil or Mylar because these balloons hold their shape without the need for a lot of pressure and because the pores between the molecules are smaller. Hydrogen Versus Helium What deflates faster than a helium balloon? A hydrogen balloon. Even though hydrogen atoms form chemical bonds with each other to become H2 gas, each hydrogen molecule is still smaller than a single helium atom. This is because normal hydrogen atoms lack neutrons, while each helium atom has two neutrons. Factors That Affect How Quickly a Helium Balloon Deflates You already know the balloon material affects how well it holds helium. Foil and Mylar work better than latex or paper or other porous materials.  There are other factors that influence how long a helium balloon remains inflated and floats. Coatings on the inside of the balloon affect how long it lasts. Some helium balloons are treated with a gel that helps hold the gas inside the balloon longer.Temperature influences how long a balloon lasts. At higher temperature, the motion of molecules increases, so the rate of diffusion (and rate of deflation) increases. Increases the temperature also increases the pressure the gas exerts on the wall of the balloon. If the balloon is latex, it can expand to accommodate the increased pressure, but this also increases the gaps between latex molecules, so the gas can escape more quickly. A foil balloon cant expand, so the increased pressure can cause the balloon to burst. If the balloon doesnt pop, the pressure means helium atoms interact more often with the balloon material, leaking out faster.
