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

The ratio of specific heats (CPCV)\left(\frac{C_P}{C_V}\right) in terms of degree of freedom (f) is given by:

Show answer and solution

Answer: (b)

  1. Cv=f2RC_v = \frac{f}{2}R, Cp=(f2+1)RC_p = \left(\frac{f}{2}+1\right)R.
  2. γ=1+2f\gamma = 1 + \frac{2}{f}
  3. So the answer is (b) (1+2f)\left(1 + \frac{2}{f}\right).
