For an ideal diatomic gas in thermal equilibrium, the ratio of the molar heat capacity at constant volume at very high temperatures to that at room temperature is equal to

Options:

Answer:

Solution:

Room temperature: $C_{V} = \frac{5 R}{2}$ (translation + rotation). Very high temperature: vibration adds R, $C_{V} = \frac{7 R}{2}$ . Ratio $= \frac{7}{5}$ .
