Question
The difference between CP and CV can be derived using the empirical relation H = U + pV. Calculate the difference between CP and CV for 10 moles of an ideal gas.
Solution
Given that, Cv = Heat capacity at constant volume,
Cp = Heat capacity at constant pressure
Difference between Cp and Cv is equal to gas constant (R).
∴ Cp – Cv = nR ......(where, n = no. of moles)
= 10 × 8.314
= 83.14J
