3 litres of dry gas was taken at a pressure of 10kg/cm2 at a constant temperature. What will be the change in volume if we increase the pressure from 10kg/cm2 to 40kg/cm2?
It will decrease from 3 litres to 3/4 litres
The volume of the gas will surely decrease from 3 litres to 3/4 litres because according to the Boyle's law the volume is inversely proportional to the pressure of the gas (P1V1 = P2V2).
