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.
✓

Answer

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).

$\therefore$ Cp - Cv = nR (where, n = no. of moles)

= 10 × 8.314 = 83.14J
