P-V Diagrams & Cyclic Processes

One mole of an ideal monatomic gas undergoes a cyclic process as shown in the figure. The total heat supplied to the gas is:

Show answer and solution

Answer: (d)

  1. In a cycle ΔU=0\Delta U = 0, so Q=WQ = W = area enclosed.
  2. W=(300−100)(5−2)=200×3=600W = (300 - 100)(5 - 2) = 200 \times 3 = 600 J; the cycle a-b-c-d is clockwise, so W>0W > 0.
  3. So the answer is (d) 600 J.
