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