Q. The $P$-$V$ diagram shows seven curved paths (connected by vertical paths) that can be followed by a gas. Which two of them should be parts of a closed cycle if the net work done by the gas is to be at its maximum value
A) $ac$
B) $cg$
C) $af$
D) $cd$
Explanation
(c) Area enclosed between $a$ and $f$ is maximum. So work done in closed cycles follows $a$ and $f$ is maximum
