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 [AMU (Engg.) 2000]
A) ac
B) cg
C) af
D) cd
Correct Answer:
C
Solution :
Area enclosed between a and f is maximum. So work done in closed cycles follows a and f is maximum.
