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

The molar specific heat of an ideal gas at constant pressure and constant volume is CpC_p and CvC_v respectively. If RR is universal gas constant and γ=CpCv\gamma = \frac{C_p}{C_v} then Cv=C_v =

Show answer and solution

Answer: (d)

  1. Mayer: Cp−Cv=RC_p - C_v = R, with Cp=γCvC_p = \gamma C_v.
  2. Cv(γ−1)=R⇒Cv=Rγ−1C_v(\gamma - 1) = R \Rightarrow C_v = \frac{R}{\gamma-1}
  3. So the answer is (d) Rγ−1\frac{R}{\gamma-1}.
