Gas Law Relationship Mathematical Formula 
(if any) 
Boyle's Law At a constant temperature, the volume of a gas in a closed system varies inversely with the pressure.  When the volume goes up, the pressure goes down and vice versa PV = constant

P1V1 = P2V2

V2=V1P1/P2

 

Charles' Law At a constant pressure, the volume varies directly with the Kelvin temperature. V/T = constant

V1/T1 = V2/T2

V2=V1T2/T1

Gay-Lussac's Law At a constant volume, the pressure varies directly with the Kelvin temperature.   P/T = constant

P1/T1 = P2/T2

P2=P1T2/T1

Combined Gas Law This a relationship combines the above gas laws.  It holds for gases in a closed system with temperature expressed in Kelvin. PV/T = constant

P1V1/T1 = P2V2/T2

V2=V1(P1/P2)(T2/T1)

Avogadro's Principle At the same temperature and pressure, an equal volume of any gas contains the same number of particles.   At STP, one mole of any gas occupies 22.4 liters. 
Ideal Gas Law A mathematical relationship that relates pressure, volume, temperature, and the number of moles for ideal gases. PV=nRT

where n= number of moles

R= Universal Gas Constant
R= 62.4 mm*L/(mole* K)
R= 8.314 L*kPa/(mole*K)
R= 0.0821L*atm/(mole*K)

Dalton's Law of Partial Pressures The total pressure of a mixture of gases is equal to the sum of the individual gases partial pressures. Ptotal = P1 + P2 + P3 + P4 + P5 +....
