A → B : Isothermal expansion at temperature T so that the volume is doubled from V1 to V2 = 2V1 and pressure changes from P1 to P2. B → C : Isobaric compression at pressure P2 to initial volume V1. C → A : Isochoric change leading to change of pressure from P2 to P1. Total work done in the complete cycle ABCA is :
