The Formula for Boyles Law

Boyles law is a special case of the ideal gas law. This law applies only to ideal gases held at a constant temperature, allowing only the volume and pressure to change. Boyles Law Formula Boyles law is expressed as:PiVi PfVfwherePi initial pressureVi initial volumePf final pressureVf final volume Because the temperature and the amount of gas dont change, these terms dont appear in the equation. What Boyles law means is that the volume of a mass of gas is inversely proportional to its pressure. This linear relationship between pressure and volume means doubling the volume of a given mass of gas decreases its pressure by half. It is important to remember the units for initial and final conditions are the same. Do not start with pounds and cubic inches for initial pressure and volume units and expect to find pascals and liters without converting the units first. There are two other common ways to express the formula for Boyles law. According to this law, at a constant temperature, the product of pressure and volume is a constant: PV c or P ∠ 1/V Boyles Law Example Problem A 1 L volume of a gas is at a pressure of 20 atm. A valve allows the gas to flow into a 12 L container, connecting the two containers. What is the final pressure of this gas? A good place to start this problem is to write out the formula for Boyles law and identify which variables you know and which remain to be found. The formula is: P1V1 P2V2 You know: Initial pressure P1 20 atmInitial volume V1 1 Lfinal volume V2 1 L 12 L 13 Lfinal pressure P2 variable to find P1V1 P2V2 Dividing both sides of the equation by V2 gives you: P1V1 / V2 P2 Filling in the numbers: (20 atm)(1 L)/(13 L) final pressure final pressure 1.54 atm (not the correct number of significant figures, just so you know) If youre still confused, you may wish to review another worked Boyles Law problem. Interesting Boyles Law Facts Boyles law was the first physical law written as an equation that described the dependence of two variables. Before this, one variable was all you got.Boyles law is also known as the Boyle-Mariotte law or Mariottes law. Anglo-Irish Boyle published his law in 1662, but French physicist Edme Mariotte came up with the same relation independently in 1679.Although Boyles law describes the behavior of an ideal gas, it can be applied to real gases at a normal temperature and low (ordinary) pressure. As temperature and pressure increase, gases start to deviate from any variation of the ideal gas law. Boyles Law and Other Gas Laws Boyles law is not the only special case of the ideal gas law. Two other common laws are  Charles law  (constant pressure) and Gay-Lussacs  law  (constant volume).

Cultural Critique- Racism - 803 Words

Brelyn E. Finley English 102.007 12- 12:50PM April 7, 2011 Professor Jackson Cultural Critique Unfortunately, in this time and age, racism continues to be an issue in the American society, especially in the south. Since the introduction of slavery, many people have the belief that skin color determines someone’s ranking in life. After the freedom of slaves, racism became a big problem in America. As a result, other races look down upon many different cultures and ethnic groups believing that they are superior to others. Racism has lead to people discriminate against one another and become prejudice. Unfortunately, racism effects peoples lifestyles, job opportunities, and education.

People carry racism to their job place, and other places creating an uneasy and negative atmosphere. Racism has shaped America into what it is today. Without racism, people would not be as strong as they are today, with thicker skin for words. Comparing people’s treatment of now to the treatment of who endured racism, the negativity is nowhere near as harsh. Racism has also caused many people to love themselves even more. There is currently a new trend of people becoming excited by their â€Å"haters;† and instead of allowing it to hurt them, they use it for motivation. America has been negatively impacted by racism. It has caused negative changes in people’s lifestyle, job opportunities, and education. Due to the negative influences of racism, people have gone into deep depressions. People have succumb to depression because they are constantly discriminated against inside and outside the work force, they have to constantly over compensate and compete for jobs with people of different races, people are called out of their name, and are being miseducated by the educational system.

Children Today free essay sample

There are many factors which lead to the way children act today. The way a child is raised, is a reflection of the lack of respect which an adolescent embraces for their elders. Over time, generations of human beings have become more reliant on technology. This has made mankind lazy and uncultured, causing a reflection on our children. Also, there have been many laws which were set against structure in a childs life. Whether the child is at home, school, or with a care giver such as a â€Å"babysitter†, there are limits to how a child can be disciplined. However, when a child has a lack of authoritative parents, it often times produces the young ones disrespect for others. The powerful painting by Banksy entitled, Girl Patting Down Army Soldier, demonstrates role reversal between child and adult. The image clearly illustrates a young girl in a pink dress and pig-tails, patting down a strong, fierce soldier. We will write a custom essay sample on Children Today or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Soldiers represent power and authority, and this little girl is taking over that roll. This, to an extent, is the way our generation of children are becoming. They believe they are equals with adults in this world. They do this by bossing their parents around, and disrespecting them day after day. The way our world uses technology is only part of the reason why our children are so ignorant today. In the past, parents would send their children outside to get their pride and joy out of their hair and to have some fresh air. Presently, they set their child in front of a television to watch a show or play a video game. Due to the fact that most parents do not monitor every show or game their child takes part of, many children begin learning how to act by observing what is on the television screen in front of them. The television show entitled, Toddlers and Tiaras, is a prime example of these types of shows. Here, children of various ages dress as though they are twenty years old, yet act the total opposite. Kids which are two and three yeas old talk back to their parents and constantly role their eyes at the people they love. There are also multiple children hitting their competition and parents when they do not get what they want. When any child watches this type of show, they often times will begin to mirror the negative behavior. In fact, according to Illinois State Medical Societys  experiment entitled, Monkey See Monkey Do, â€Å"In a matter of seconds, most children can mimic a movie or TV character, sing an advertising jingle or give other examples of what they have learned from watching media. These examples may include naming a popular brand of beer, striking a â€Å"sexy† pose, acting impolitely, or play fighting. Children only have to put a movie into the DVD player, flip through the channels, open a magazine, click on a web site, pop a video game into an X-Box or watch television to experience all kinds of messages. The impact of these messages can build slowly when children see and hear them over and over again.† Our youth today does not understand what is real and what is not on the T.V. If kids do not have guidance from their parents, they will most likely begin transforming into impolite little people. Therefore, parents need to not place their child in front of the television, but rather spend more time with them. Many kids care givers are also beginning to spend more time with their technology instead of their child. This is beginning to cause children to act up due to the fact they feel they are getting no attention. An article on The Washington Post entitled, Parents are ignoring their children for their Blackberry, stated, If youre taking [parental attention] away from the child, for what looks like it is not a good reason, kids might think, What am I doing wrong that my parents dont like me? and may start acting out to get their parents attention because they have a hard time distinguishing positive from negative attention. Although parents do not mean to push their child away and make them feel as though they are less important than their phone, they are. This is why our generation of kids are beginning to throw tantrums and are becoming more impolite. The laws which have been set against a childs punishment have changed tremendously over the past fifty years. This is a large factor of why our children have become so disrespectful to the people around them. In the past, teachers had the right to inflict corporal punishments on children. This is a form of discipline which ended around 1989 in Oregon. According to American Academy of Child and Adolescent Psychiatry, corporal punishment is a method which a, â€Å"Supervising adult deliberately inflicts pain upon a child in response to a childs unacceptable behavior.† The purpose for this  type of punishment was to try to prevent non-tolerated actions to reoccur. It was meant to change their long-term behaviors and to show the child what was and was not acceptable. In current times, children can not be touched in any physical matter from any one other than their parent or guardian. This is because it is now illegal to physically harm kids. This law has led some children to understand they can get away with excessive amounts of negative behaviors due to the fact there are less ramifications that follow their unfavorable actions. Because of these laws, kids can not be disciplined to any amount which the state would find excessive. Therefor, when these kids become disrespectful, there is no possible way for the children to be disciplined by any teacher or caregiver. The law of non corporal punishment has effected our children to a point because they cannot be punished for their actions, making them more disrespectful. There are many parents who hold a lack of authority. This is part of what is producing our youths disrespect for others. An authoritative parent is someone who expects a lot from their child. They also have strict rules which they predict will be followed at all times. These parents are also a large part of child rearing. According to ChildRearingMatters.com, â€Å"The aim is always to bring out the best in each child, and to prevent and overcome difficulties.† In other words, parenting. When a childs parents lack this, their children in most cases, end up running the house. These children think they are their own parent. When this occurs, the adolescent ends up pushing their own parents around as well as the others around them. Many children today are becoming unexceptionably disrespectful to their elders and others around them. This is due to the way they are raised and brought up since birth. There are three main aspects which have created this issue which is occurring now. These include the number of parents relying on technology, the laws which protect children from any form of physical discipline, and the lack of authoritative parents which these children have. If the way our children are raised never changes, the issue of disrespect towards others is only going to worsen. Having respect for other is a large aspect of life. If children can not learn how to respect others, how are they supposed to respect themselves?

The Beautiful and Damned Quotes

'The Beautiful and Damned' Quotes The Beautiful and Damned is the second novel, published by F. Scott Fitzgerald. The book is about Anthony Patch, a socialite during the 1920s Jazz Age. Here are quotes from the famous classic. The Beautiful and Damned Quotes The victor belongs to the spoils. In 1913, when Anthony Patch was twenty-five, two years were already gone since irony, the Holy Ghost of this later day, had, theoretically at least, descended upon him. As you first see him he wonders frequently whether he is not without honor and slightly mad, a shameful and obscene thinness glistening on the surface of the world like oil on a clean pond, these occasions being varied, of course, with those in which he thinks himself rather an exceptional young man, thoroughly sophisticated, well adjusted to his environment, and somewhat more significant than anyone else he knows. This was his healthy state and it made him cheerful, pleasant, and very attractive to intelligent men and to all women. In this state, he considered that he would one day accomplish some quiet subtle thing that the elect would deem worthy and, passing on, would join the dimmer stars in a nebulous, indeterminate heaven half-way between death and immortality. Until the time came for this effort he would be Anthony Patch - not a portrait of a man but a distinct and dynamic personality, opinionated, contemptuous, functioning from within outward - a man who was aware that there could be no honor and yet had honor, who knew the sophistry of courage and yet was brave. To Anthony life was a struggle against death, that waited at every corner. It was as a concession to his hypochondriacal imagination that he formed the habit of reading in bed - it soothed him. He read until he was tired and often fell asleep with the lights still on. Curiously enough he found in senior year that he had acquired a position in his class. He learned that he was looked upon as a rather romantic figure, a scholar, a recluse, a tower of erudition. This amused him but secretly pleased him - he began going out, at first a little and then a great deal. Once upon a time all the men of mind and genius in the world became of one belief that is to say, of no belief. But it wearied them to think that within a few years after their death many cults and systems and prognostications would be ascribed to them which they had never meditated nor intended. Lets join together and make a great book that will last forever to mock the credulity of man. Lets persuade our more erotic poets to write about the delights of the flesh, and induce some of our robust journalists to contribute stories of famous amours. Well include all the most preposterous old wives tales now current. Well choose the keenest satirist alive to compile a deity from all the deities worshipped by mankind, a deity who will be more magnificent than any of them, and yet so weakly human that hell become a byword for laughter the world over and well ascribe to him all sorts of jokes and vanities and rages, in which hell be supposed to indulge for his own diversion, so that the people will read our book and ponder it, and therell be no more nonsense in the world. Finally, let us take care that the book possesses all the virtues of style, so that it may last forever as a witness to our profound skepticism and our universal irony. So the men did, and they died. But the book lived always, so beautifully had it been written, and so astounding the quality of imagination with which these men of mind and genius had endowed it. They had neglected to give it a name, but after they were dead it became known as the Bible.
