An ideal gas of total mass and molecular weight is isochorically (at constant volume) cooled to a pressure times smaller than the initial pressure P1. The gas is then expanded at constant pressure so that in the final state the temperature T2 coincides with the initial temperature T1. Calculate the work done by the gas.
