Specific Heats of Gases - Cp, Cv, γ & Mayer's Relation

The correct relation between the degrees of freedom f and the ratio of specific heat γ\gamma is:

Show answer and solution

Answer: (a)

  1. γ=1+2f\gamma = 1 + \frac{2}{f}
  2. f=2γ−1f = \frac{2}{\gamma-1}
  3. So the answer is (a) f=2γ−1f = \frac{2}{\gamma-1}.
