P-V Diagrams & Cyclic Processes

A thermodynamic system is taken from state AA to BB along ACBACB and is brought back to AA along BDABDA as shown in the PVPV diagram. The net work done during the complete cycle is given by the area

Figure

Show answer and solution

Answer: (c)

  1. Net work in a cycle = area enclosed by the closed loop on the PP-VV diagram.
  2. The loop is A→C→B→D→AA \to C \to B \to D \to A.
  3. So the answer is (c) ACBDAACBDA.
