Question

The P-V diagram of a gas undergoing a cyclic process (ABCDA) is shown in the graph, where P is in $N{m}^{-2}$ and V in $c{m}^3$. Identify the incorrect statement.

• A. 0.4 J of work is done by the gas from A to B.
• B. 0.2 J of work is done by 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 from B to C. on the gas from D to A.

Answer 1

The correct option is D Work is done by the gas from B to C. on the gas from D to A.

Since volumes remain constant during the process BC and DA.So work done by the gas during these processes is zero.

So option D is correct.
