Five moles of ail ideal gas has pressure P0, volume V0 and temperature T0. The gas is expanded to volume 3V0 along a path so that the pressure P is changed as function of volume V as P=P0(V/V0). The pressure is then reduced to P0 maintaining the volume constant. The gas undergoes an isobaric compression till the volume & temperature become V0 & T0 respectively. The total work done by the gas during the entireprocess is
