Dalton's Law of Partial Pressure
at constant volume and temperature, the total pressure exerted by a mixture of gasses is equal to the sum of the partial pressure of the gasses
partial pressure
pressure contributions from each gas in a mixture make the total pressure of the mixture (Ptotal = P1 + P2)
Boyle's Law
when the number of particles and temperature are constant, pressure and volume are inversely proportional (P1V1=P2P2)
(Jacques) Charles's Law
the volume of a fixed mass of a gas is directly proportional to its Kelvin temperature if the pressure is constant (V1/T1=V2/T2)
expanding gas
endothermic
compressing gas
exothermic
(Joseph Louis) Gay-Lussac's Law
pressure of a given mass of gas is directly proportional to the Kelvin temperature if the volume is constant (P1/T1=P2/T2)
Combined Gas Law
(P1V1)/T = (P2V2)/T2
