Final answer:
The heat capacities of a perfect gas are related by Cp = Cv + R.
Step-by-step explanation:
The heat capacities of a perfect gas are related by the equation Cp = Cv + R. Cp represents the molar heat capacity at constant pressure, Cv represents the molar heat capacity at constant volume, and R is a constant known as the gas constant. This relationship holds true for all dilute gases, including monoatomic, diatomic, and polyatomic gases.
