A gas taken through the cycle A → B → C → A, as shown, what is the net work done by the gas?

Option A -2000 J
Option B 2000 J
Option C 1000 J
Option D zero

Solution: Correct Option C

The total work done in a cyclic process equals the area of the triangle ABC.
If the process runs clockwise, the amount of work completed will be positive; otherwise, it will be negative. In this case, the work is carried out in a clockwise direction.

Area under P-V curve. = 1000 J
