WebFrom A to B, the pressure is constant at p, so the work over this part of the path is. W = ∫ V 1 V 2 p d V = p 1 ∫ V 1 V 2 d V = p 1 ( V 2 − V 1). From B to C, there is no change in volume and therefore no work is done. The net work over the path ABC is then. W = p 1 ( V 2 − V 1) + 0 = p 1 ( V 2 − V 1).
