The specific heat at constant volume for a diatomic gas is typically 5R/2. The specific heat ratio, or gamma (γ), is defined as the ratio of the specific heat at constant pressure to the specific heat at constant volume. Therefore, for a diatomic gas with (C_v = \frac{5R}{2}), the gamma will be (\gamma = \frac{C_p}{C_v} = \frac{7R/2}{5R/2} = \frac{7}{5}) or 1.4.
