A gas is taken through the cycle A B C A , as shown in figure. What is the net work done by the gas?

Options

  1. A2000 ~J
  2. B1000 ~J
  3. CZero
  4. D-2000 ~J

Correct answer

B. 1000 ~J

Step-by-step solution

Net work done by the gas = Area enclosed in p-V curve, i.e. area of A B C . W_ net = 1 2 5 10⁻³ 4 10^5 ~J =10^3 ~J =1000 ~J
