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

The ratio of the specific heats CpCv=γ\frac{C_p}{C_v} = \gamma in terms of degrees of freedom (n) is given by

Show answer and solution

Answer: (a)

  1. Cv=n2RC_v = \frac{n}{2}R, Cp=(n2+1)RC_p = \left(\frac{n}{2}+1\right)R.
  2. γ=1+2n\gamma = 1 + \frac{2}{n}
  3. So the answer is (a) (1+2n)\left(1 + \frac{2}{n}\right).
