Physics · Thermodynamics
n moles of an ideal gas undergo a cyclic process ABCA consisting of the following three steps: 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 back to the initial volume V1. C → A: Isochoric change leading to a change of pressure from P2 to P1. The total work done in the complete cycle ABCA is given by:
