Question

Quizplus · Accepted Answer

For an ideal gas, the difference in the molar heat capacity at constant P and constant V is given by the Mayer's formula: Cp - Cv = R, where Cp is the molar heat capacity at constant pressure, Cv is the molar heat capacity at constant volume, and R is the gas constant. This equation holds true for all gases, regardless of whether they are monoatomic, diatomic, or polyatomic, as long as they can be approximated as an ideal gas. Therefore, the best choice is E) A) and D), which states that the difference is equal to R for all gases.
