Suppose a gas occupies volume V1 when its pressure is P1;then
V1 is directly proportional to 1/P1 or V1 = k/P1
or P1V1 = k = constant
If V2 is the volume occupied when the pressure is P2 at the same temperature,then
V2 is directly proportional to 1/P2 or V2 = k/P2
or P2V2 = k = constant
:. P1V1 = P2V2 = k, at constant temperature
