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

Specific heats of an ideal gas at constant pressure and volume are denoted by CpC_p and CvC_v respectively. If γ=CpCv\gamma = \frac{C_p}{C_v} and RR it's the universal gas constant then CvC_v is equal to

Show answer and solution

Answer: (d)

  1. Cp−Cv=RC_p - C_v = R and 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) R(γ−1)\frac{R}{(\gamma-1)}.
