Vedclass · Answer

(B) The work done in a thermodynamic process is equal to the area under the $p-V$ curve.For a cyclic process,the net work done is equal to the area enclosed by the cycle.If the cycle is traversed in a clockwise direction,the net work done is positive.If the cycle is traversed in a counter-clockwise (anticlockwise) direction,the net work done is negative.In the given figure,the path is $C \rightarrow B \rightarrow A \rightarrow D \rightarrow C$,which is counter-clockwise.Therefore,the net work done by the gas is negative.
