The `P-V` diagram of a gas undergoing a cyclic process ABCDA is shown in (figure). Where `P` is in `N//m^(2)` and `V` is in `cm^(3)`. Identify the incorrect statement

Options

A. `0.4J` of work is done by the gas from A to B
B. `0.2J` of work is done on the gas from C to D
C. No work is done by the gas in going from B to C
D. Work done by the gas in going from B to C and on the gas from D to A

Answer

D

Explanation

The incorrect statement is (d).This is because, in going from B to C or D to A, `dV=0`
`:. dW= P.dV=0`
