For a gas R C v = 0.4 , where R is the universal gas constant and C v is the molar specific heat at constant volume. The gas is made up of molecules which are

Options

  1. Arigid diatomic
  2. Bmonoatomic
  3. Cnon- rigid diatomic
  4. Dpolyatomic

Correct answer

A. rigid diatomic

Step-by-step solution

R C v = 0.4 ⇒ C p - C v C v = 0.4 C p C v - 1 = 0.4 ∴ C p C v = 1.4 ⇒ γ = 1.4 As γ = 1.4 , the gas is diatomic in nature. Example, air molecules.
