Question

Area enclosed by a cycle on a P-V diagram represents:
  1. A
    Total heat absorbed
  2. B
    Total work done by gas
    Correct
  3. C
    Change in internal energy
  4. D
    Total entropy change

Correct answer

Total work done by gas

Explanation

Work W = ∮PdV = area enclosed by the cycle on P-V diagram. Sign depends on direction (clockwise = positive work = engine).
