Chemistry: The Behavior Of Gases Essay

1171 words - 5 pages

Early scientists were the easiest to describe the gaseous state. The gaseous state first began to be described during late 1662. The gaseous state led to many mathematical equations and formulas that can be applied to all, if not most, gases. In this essay many topics will be discussed. My main focus will include some properties of gases, and explain how the behaviors of gases differ as variables are included.
Gases surround us humans every single day. Many times we overlook gases because it is not something we pay very close attention to. The Earth's atmosphere is what keeps up alive and living each day. The atmosphere is one of the most valuable gas samples to us humans because it ...view middle of the document...

The reason gases can expand is because of diffusion. Because expandability allows the gases to fill the container we can assume that the volume of the container and the amount of gas inside are equal.
The final property of gases is that they occupy more space than the liquids or solids they form. The volume of liquids increases by eight hundred times while it is forming into a gas. The large amount of volume change is used in many different ways. Those were the three properties in the behavior of gases.
Gas Laws and the behavior of gases with the changes of pressure, temperature, volume and number of particles. The gas Laws explain the concept clearly and in description. The Boyle’s Law: pressure – volume law, at a volume of given amount a gas held at a constant temperature varies inversely with the applied pressure. The temperature and mass would be held as a constant. The formula used would be PV=C. As the pressure begins to
move up, the volume will act in the opposite way and begin to decrease. Or if the volume moves up the pressure will move down. Volume and temperature in Boyle’s Law react opposite of each other.
Another law, Charles’ law: temperature- volume law explains the changes in temperature. The volume amount law, Avogadro’s law explains the changes in volume. Daltons Law of Partial Pressure states that the total pressure of a mixture with no reacting gases is the sum of all of the individual pressures. Ptotal=Pa+Pb+Pc+Pd… This law is many times used to determine any proportions involving the gases.
The equations that we are given from the gas laws are what explain all of the variables to us. The scientists whose names are given to the laws are the ones who are responsible for these mathematical equations, such as PV=C. These scientists are the one who have given us the reasoning to the relationship to each of the variables with one another.
An important theory that explains the behavior of all gases in terms of atomic and molecular motion is the Kinetic Molecular Theory. This theory states that a gas is composed of many large molecules that are in continuous motion. The particles will sometimes collide with each other or the container. The result from the collisions will be a force that the particle will exert from the wall. This theory also describes the behavior of gases colliding with...
