8. Heat Capacity Ratios for Gases (Cp/Cv) - …

The heat capacity at constant volume, Cv, is the derivative of the internal energy with respect to the temperature, so for our monoatomic gas, Cv = 3/2 R. The heat capacity at constant pressure can be estimated because the difference between the molar Cp and Cv is R; Cp – Cv = R. Although this is strictly true for an ideal gas it is a good
