chemistry: Gas Laws

The ideal gas law

An ideal gas is modeled on the kinetic theory of gases which has 4 basic postulates: gases consist of small particles which are in continuous random motion, the volume of the molecules present is negligible compared to the total volume occupied by the gas, intermolecular forces are negligible, pressure is due to the gas molecules colliding with the walls of the container. The mathematical equation used to represent the ideal gas law is PV=nRT

Charles' Law

Charles' Law tells us that temperature and volume vary directly with each other. This holds true at constant pressure. Temperature for all Charles' Law problems must be in Kelvin. As the temperature of a gas increases, it gains energy. This will result in an increase in contacting the sides of their containers they are going to want to expand. The mathematical formula that represents this relationship is V1/T1=V2/T2.

Avagadro's Law

Avagadro's Law tells us that for a gas at constant temperature and pressure, the volume is directly proportional to the number of moles of gas present. Equal volumes of gases at the same temperature and pressure have the same number of particles. The mathematical formula for this relationship is V1/N1=V2/N2

Boyle's gas law

Boyle's Law tells us that the relationship between pressure and volume is an inverse relationship. It deals with two of the four factors that determine the state of a gas: pressure and volume. It holds true at at constant temperature. The mathematical equation that is used to express this relationship is P1V1=P2V2.
