The molar heat capacity of a monatomic ideal gas is independent of temperature and pressure.

Question

Quizplus · Accepted Answer

The molar heat capacity of a monatomic ideal gas is independent of temperature and pressure, as it depends only on the number of degrees of freedom of the gas particles, which is 3 for monatomic gases. This means that the molar heat capacity at constant volume (Cv) is always 3/2 R, and the molar heat capacity at constant pressure (Cp) is always 5/2 R, where R is the gas constant.
