Class 11PhysicsKinetic Theory of GasesMolar Specific Heat of gas and relation between them (Mayer's formula)
EasySpecific heats of an ideal gas at constant pressure and volume are denoted by $C_p$ and $C_v$ respectively. If $\gamma = \frac{C_p}{C_v}$ and $R$ is the universal gas constant,then $C_v$ is equal to:
- A$\frac{(\gamma-1)}{(\gamma+1)}$
- B$\frac{(\gamma-1)}{R}$
- C$R \gamma$
- D$\frac{R}{(\gamma-1)}$
