Quizplus · Accepted Answer

The ratio of the specific heat of an ideal gas at constant volume (Cv) to its specific heat at constant pressure (Cp) is not directly given by R or 1/R, nor is it dependent on temperature or pressure for an ideal gas. However, it does vary based on the molecular structure of the gas, such as whether it is monatomic, diatomic, or polyatomic, because the degrees of freedom of the gas molecules affect their specific heats.
