Question

A cycle PQRS has P → Q expansion at constant pressure, Q → R pressure drop at constant volume, R → S compression at constant pressure and S → P pressure rise at constant volume. Work is done on the gas in:

TestHub · Accepted Answer

Work is done on the gas only when its volume falls. That is along RS . In QR and SP the volume is constant, so W = 0 . A.
