n mole of perfect gas undergoes a cyclic process ABCA (see figure) consisting of the following processes.
A->B : Isothermal expansion at temperature T so that the volume is doubled from V1 to V2 and Pressure changes from P1 to P2.
B->C : Isobaric compression at pressure P2 to initial volume V1.
C->A : Isobaric change leading to change of pressure from P2 to P1.
Total work done in the complete cycle ABCA is:
