A thermodynamics system undergoes cyclic process A B C D A as shown in Figure. The work done by the system in the cycle is:

Options

  1. AP 0 V 0
  2. B2 P 0 V 0
  3. CP 0 V 0 2
  4. DZero

Correct answer

D. Zero

Step-by-step solution

Work done in process O D A = 1 2 × P 0 × V 0 While work done in the process O B C = - 1 2   P 0 V 0 Net work done = 0
