Using the given P - V diagram, the work done by an ideal gas along the path ABCD is :

Options

  1. A3 P ₀ ~V ₀
  2. B-4 P ₀ ~V ₀
  3. C-3 P ₀ ~V ₀
  4. D4 P ₀ ~V ₀

Correct answer

C. -3 P ₀ ~V ₀

Step-by-step solution

Area under graph will be magnitude of graph and being counterclockwise graph it would be negative aligned & Area =2 P₀ V₀+P₀ V₀=3 P₀ V₀ & ~W =-3 P₀ V₀ aligned
