The ratio of the adiabatic to isothermal elasticities of a triatomic (non-linear) gas is

Options

  1. A(3: 4 )
  2. B(1: 2 )
  3. C(4: 3 )
  4. D(5: 3 )

Correct answer

C. (4: 3 )

Step-by-step solution

For triatomic non-linear gas degree of freedom, (f=6 ) ( aligned & C_V= f R 2 = 6 R 2 =3 R C_p & =C_V+R=3 R+R=4 R aligned ) ( ) Ratio of adiabatic to isothermal elasticities of a triatomic (non-linear) gas is ( = C_p C_V = 4 R 3 R = 4 3 )
