Which one of the following statements is true concerning the ratio of the molar heat capacities C_p/C_vfor an ideal gas?

Question

Quizplus · Accepted Answer

For an ideal gas, the ratio of molar heat capacities C_p/C_v (also known as the heat capacity ratio or gamma, γ) is always greater than 1. This is because C_p includes the work done by the system during expansion at constant pressure, in addition to the heat required to raise the temperature, whereas C_v only includes the heat required to raise the temperature at constant volume.
