When equal volumes of helium and neon at same temperature and pressure are mixed, the ratio C_p: C_V of the mixture equals

Options

  1. A3: 5
  2. B1: 2
  3. C5: 3
  4. D2: 1

Correct answer

C. 5: 3

Step-by-step solution

Equal volume of He and Ne are mixed which are monoatomic gases. C_p is molar specific heat capacity at constant pressure. C_V is molar specific heat capacity at constant volume. Degree of freedom (f) for monoatomic gas =3 aligned & C_p C_V =1+ 2 f =1+ 2 3 = 5 3 & C_p C_V = 5 3 aligned
