Vedclass · Answer

(D) In a $P-V$ diagram,the work done by the gas is given by the area under the 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 by the gas is positive. If the cycle is traversed in a counter-clockwise direction,the net work done by the gas is negative. Looking at the provided $P-V$ diagram,the cycle $ABCDA$ is traversed in a clockwise direction. Therefore,the net work done by the gas in the cycle $ABCDA$ is positive.

The figure shows the $P-V$ plot of an ideal gas taken through a cycle $ABCDA.$ The part $ABC$ is a semicircle and $CDA$ is half of an ellipse. Then,
