One mole of a diatomic gas does a work Q 3 , when the amount of heat supplied is 'Q'. In this process, the molar heat capacity of the gas is

Options

  1. A15 R 4
  2. B9 R 4
  3. C7 R 4
  4. D3 R 4

Correct answer

A. 15 R 4

Step-by-step solution

The amount of heat required to increase the internal energy is ( Q - Q 3 )= 2 3 Q For a diatomic gas, the amount of heat required to increase the internal energy is C_ v = 5 2 R array l 2 3 Q= 5 2 R Q= 15 4 R array
