Question
The pressure-volume diagram shows six curved paths that can be followed by the gas (connected by vertical paths). Which two of them should be part of a closed cycle if the net work done by the gas is to be its maximum positive value?

A.
$$af$$
B.
$$ae$$
C.
$$ac$$
D.
$$ce$$
Answer :
$$ae$$
Solution :
Work done in expansion is positive and in compression it is negative.
Work done in expansion is positive and in compression it is negative.
