The molar specific heat capacity of a diatomic gas at constant pressure is C . The molar specific heat capacity of a monoatomic gas at constant volume is

Options

  1. A2 C 7
  2. B3 C 7
  3. CC 7
  4. D4 C 7

Correct answer

B. 3 C 7

Step-by-step solution

For diatomic gas, f ₁=5C_ v₁ = f₁ R 2 = 5 R 2 C_ p₁ =C_v+R= 5 R 2 +R 7 R 2 =C For monoatomic gas, f ₂=3C_ v₂ = f₂ R 2 = 3 R 2 Now, C C _ v ₂ = 7 R 2 3 R 2 = 7 3 C_ v₂ = 3 C 7
