P-V Diagrams & Cyclic Processes

An ideal monoatomic gas is taken around the cycle ABCDA as shown in the P.V diagram. The work done during the cycle is

Figure

Show answer and solution

Answer: (c)

  1. Net work in a cycle = area enclosed on the P-V graph.
  2. Area =(2P0−P0)(3V0−V0)=2P0V0= (2P_0 - P_0)(3V_0 - V_0) = 2P_0V_0.
  3. A to B (bottom, rightwards), B to C (up), C to D (top, leftwards), D to A (down) is anticlockwise, so the work is negative.
  4. So the answer is (c) −2P0V0-2P_0V_0.
