The P-T graph as given below was observed for a process of an ideal gas, which of the following statement is true?

Options

  1. Aw = + v e , Δ H = + v e
  2. Bw = - v e , Δ H = - v e
  3. Cw = - v e , Δ H = + v e
  4. Dw = + v e , Δ H = - v e

Correct answer

C. w = - v e , Δ H = + v e

Step-by-step solution

V B > V A a n d T B > T A Δ H = n c p ( T B - T A ) > 0 w = - p e x t V B - V A < 0
