The p-V diagram of a Carnot's engine is shown in the graph below. The engine uses 1 mole of an ideal gas as working substance. From the graph, the area enclosed by the p - V diagram is [The heat supplied to the gas is 8000 ~J ]

Options

  1. A1200 ~J
  2. B2000 ~J
  3. C3000 ~J
  4. D1000 ~J

Correct answer

A. 1200 ~J

Step-by-step solution

[Hint Area enclosed by p-V diagram is equal to work done] Total work done by gas in one carnot cycle is given by. W= R T₁ V₂ V₁ - R T₂ V₃ V₄
