P - V diagram of a diatomic gas is a straight line parallel to P -axis. The molar heat capacity of the gas in the process will be

Options

  1. A4 R
  2. B2.5 R
  3. C3 R
  4. D4 R 3

Correct answer

B. 2.5 R

Step-by-step solution

The process described is isochoric ∴ molar heat capacity C V = 5 2 R = 2.5 R
