measuring the temperature, pressure, mass, and volume in a gaseous state. The equation used to determine the molar mass is derived from the Ideal Gas Law equation. The objective of this experiment aims to determine the molecular mass of a

athletes taking part in the risk culture are lifestyle choices. Athletes taking part in sport specific risk behaviours for victory is becoming a social health problem. The risks taken to search for the normalized image are because of social and self pressures as well as the use of performance enhancing drugs. We see in everyday life that athletes are pushing themselves to strive for victory, and a reason for this is because they feel pressured from society. People are continuing to search for the ideal

Volume and Temperature of a Gas By: Jasmine Camacho In this experiment I used both the Boyle’s and the Charles gas laws. Boyle's law states “the volume of a given quantity of a gas varies inversely as the pressure, the temperature remaining constant”. The formula used to help complete this process is PV=constant. Charles law help explain the relationship between temperature and gas volume. And the formula for this is V/T=constant. For this experiment I used the ideal gas law; pV=nRT.

states that the number of moles are proportional to the volume of a gas at a constant temperature and pressure. V = kn where k is the constant of proportionality. Avogadro introduces the idea of particles and how they combine and react in a chemical reaction. A soft drink is an example of Avogadro’s law. When the soft drink is shaken molecules will be released into the air. Therefore the pressure in the bottle is proportional to the number of moles of molecules in the bottle. Boyle’s Law published

Determining the Molar Volume of a Gas Lab Report The purpose of the experiment is to determine the molar volume of hydrogen gas at standard pressure and temperature. Excess hydrochloric acid was placed in a eudiometer and decanted with deionized water. A piece of magnesium ribbon was trapped in a copper wire cage in the eudiometer in order to keep it in place as the more dense hydrochloric acid diffused downward in the inverted eudiometer. The eudiometer was placed in a water bath and the magnesium

“P1V1 = P2V2” shows that as the volume increases, the pressure of the gas decreases in proportion, as long as the temperature stays the same. The relationship between pressure and volume was first noticed by mathematician and astronomer Richard Towneley and experimenter Henry Power. Robert Boyle, a chemist and physicist, confirmed the discovery and published the results in 1662. According to science historians, Boyle’s assistant, Robert Hooke, built the experimental rig. The law is based on air

Kaydyn Dillbeck IDLA Physical Science 10/26/14 Questions for U4A1 Section 1: 1. Kinetic molecular theory- used to explain the behavior of gases and is based upon the following postulates: • Gases are composed of a many particles that behave like hard spherical objects in a state of constant, random motion. • These particles move in a straight line until they collide with another particle or the walls of the container. • These particles are much smaller than the distance between particles,

You take a huge breath in your scuba mask. You dive into the water you, open your eyes. It’s all bright and colorful. You see multiple animals. There is some that are ugly but you see the most beautiful fish. You wonder what happened to it.: Say you’re in that scenario. You like what 's under the surface. Oceanic animals have many benefits and doubts most people don 't understand why or what it happening to these animals. These ocean animals are impacting the earth in multiple ways. Are they impacting

The volume, temperature and pressure exerted by a particular gas are highly dependent on one another. This is explained by several Gas Laws. Boyle’s Law states that when the temperature is kept constant, pressure of gas is inversely proportional to the volume. Relating this principle to molar volume, the higher the pressure, the smaller the volume the gas particles occupies. When the volume of the container enclosing the gas is reduced, there are more gas particles per unit volume. The gas particles

In this tragic novel. The power of love and comfort outweighs all moral principles and the willingness of the animals to follow blindly even when those they follow are corrupt. Napoleon, Squealer, the pigs and the dogs exert power and the other animals such as Boxer, Clover, Benjamin, Muriel, and the sheep are willing to follow blindly. The pigs had decided that the apples and the milk will be set aside for them. As the pigs were the brainworkers of the farm. "All animals are equal, but some animals

Marxist Perspective: Controlling Factors Even in today’s society, money is widely accepted to be the most important factor in one’s decisions. Ranging from everyday decisions such as where to eat, to even political elections, it is widely accepted that money controls all. A world without the concept of money is almost impossible to comprehend due to the importance we have placed on it as a society and as a species. Money and socio-economic power are crucial to understanding the decisions of human

The Tell-Tale Heart, written by Edgar Allan Poe, is a horror short story read by many. The point of view in Poe’s short story is unique because the unnamed narrator reveals himself as an unreliable first and second person narrator as well as an all-knowing narrator. Poe has skillfully incorporated different narrations into his short story because it helps the reader truly understand the narrator’s mental state. The multiple narrations give the reader access to the narrator’s constant stream of thoughts

Youth football is a sport that is played in many places, many people think that it is not dangerous and kids should be able to play, while others think that this sport is too dangerous and should not be played. Based off of all the evidence that I have found through research, it has let me to agreeing with the fact that youth football is too dangerous for young children to be playing. This sport has pros to it, some of which are very good, but the con side outways it, these are the things showing

Margaret Thatcher was a Conservative Prime Minister of the United Kingdom between 1979 and 1990. Three years after her resignation as Prime Minister, Margaret Thatcher published her first memoir titled The Downing Street Years. The Downing Street Years focuses on the Iron Lady’s years as British Prime Minister (1979-1990) giving glimpses into her life as the political leader of the United Kingdom. Two years later in 1995, Thatcher published her second memoir, The Path to Power that covers her life

Your shoes Your shoes Is a short story by Michele Roberts about a mother writing a letter to her daughter who has left home and how she reflects on her own life, past and family Michele Roberts as a writer interested in women´s rights and how they were treated before. In an interview for the BBC, she says: "The way that women were treated in the religion I grew up in, which was Catholicism, made me a writer - because women were seen as the source of evil in the world, the source of sin. We led

Synopsis This experiment is the determination of Calcium Carbonate (CaCO3) content in toothpaste with the use of back titration while demonstrating quantitative transfer of solids and liquids. A accurately weighed quantity of toothpaste was dissolved in excess volumes of HCl. This solution is then titrated with NaOH to find the volume of the excess HCl. The volume of HCl reacted, which is found by substracting the volume of given HCl with the volume of excess HCl reacted, can be further manipulated

transitional phase from a child to an adult, is marked as the main time period where individuals decide the path of their life. Teenagers go through, and are expected to cope with hormonal changes, puberty, social and parental forces, work and school pressures, as well as many conditions and problems. In Budge Wilson’s short story The Metaphor, and Jillian Horton’s short story The Bicycle, the main characters, Hannah and Charlotte, are experiencing the effects of adolescence first hand.

factor that could affect the outcome of the experiment would be taking the cork with the small hole in the top off and putting the other cork on and losing some of the gas. Gas could also be lost when taking the cork off for a second so that the pressure inside the flask can become equal to that of the room. This would cause the average molecular mass of the unknown gas to be less than it should be because some of the gas would be lost and replaced with air which weighs less. Another way in which

Name Instructor Course Date Absolute Zero Introduction In this lab, temperature and pressure measurements as well as the Ideal Gas Law will be used to extrapolate the absolute zero value on the Celsius scale. Theoretical Background The interaction of molecules via random collisions creates an ideal gas where the temperature, T, volume, V, and pressure, P, relate according to equation [1]. For a rigid container, the volume is assumed to be constant, where equation [1] can be rewritten as shown in

of the tree, then Boyle's, Gay- Lussac's , and Avogadro's gas laws are the 'branches'. To better understand this analogy, it is important to understand how each of the laws can be derived from the Ideal Gas Law. Gay-Lussac's law states that the pressure of an ideal gas is directly proportional to its temperature in kelvin, assuming that the amount of gas and the volume of the gas remain constant. The equation for Gay-Lassac's law would look something like: V = T k, where V is volume, T is temperature
