**Boyle’s Law:** The volume of a given mass of a dry gas is inversely proportional to its pressure at a constant temperature.

P1VI = P2V2 = k at a constant temperature.

**Charles’s Law:** The volume of a given mass of a dry gas is directly proportional to its absolute temperature if the pressure is kept constant. V1/T1 = V2/T2 = k at constant pressure
