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

For a gas having 'XX' degrees of freedom, 'γ\gamma' is (γ=\gamma = ratio of specific heats =CP/CV= C_P/C_V)

Show answer and solution

Answer: (c)

  1. Cv=X2RC_v = \frac{X}{2}R, Cp=(X2+1)RC_p = \left(\frac{X}{2}+1\right)R.
  2. γ=1+2X\gamma = 1 + \frac{2}{X}
  3. So the answer is (c) 1+2X1 + \frac{2}{X}.
