The molar 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 is the universal gas constant, then CVC_V is equal to

Options

  1. A1+γ1−γ\frac{1+\gamma}{1-\gamma}
  2. BR(γ−1)\frac{R}{(\gamma-1)}
  3. C(γ−1)R\frac{(\gamma-1)}{R}
  4. DγR\gamma R

Correct answer

B. R(γ−1)\frac{R}{(\gamma-1)}

Step-by-step solution

The value of CV=Rγ−1C_V=\frac{R}{\gamma-1}
