The molar specific 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:
| 1. | \(\dfrac{R}{\gamma -1}\) | 2. | \(\dfrac{\gamma -1}{R}\) |
| 3. | \(\gamma R \) | 4. | \(\dfrac{\left ( \gamma -1 \right )R}{\left ( \gamma +1 \right )}\) |
