Compressibility
A measure of how much the volume of matter decreases under pressure
Boyle's Law
For a given mass of a gas at constant temperature, the volume of the gas varies inversely with pressure P1 xV1 = P2 x V2
Charle's Law
The volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant V1/T1 = V2/T2
Gay-Lussac's Law
The pressure of a gas is directly proportional to the Kelvin temperature if the volume is constant P1/T1 = P2/T2
Combined Gas Law
The law that describes the relationship among the pressure, temperature, and volume of an enclosed gas (P1 x V1) / T1 = (P2 x V2) / T2
Ideal gas
A gas that conforms to the ideal gas law. Conforms exactly to all of the assumptions of the kinetic theory
Ideal gas law
The relationship PV = nRT which describes the behavior of an ideal gas
Ideal gas constant
The constant in the ideal gas law, has the symbol R and the value 8.31 (L x KPa)/(K x Mol)
Real gas
Differ from ideal gases at low temperatures and high pressures, do not exactly meet the assumptions of the kinetic theory
