Highly selective Backlog Qs for JEE MainPhysicsThermodynamics

A thermodynamical system is changed from state ( P ₁, ~V ₁ ) to ( P ₂, ~V ₂ ) by two different process, the quantity which will remain same will be

Options

  1. AQ
  2. BW
  3. CQ + W
  4. DQ - W

Correct answer

D. Q - W

Step-by-step solution

For all process U = Q - W does not change as it depends on initial final states.
