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.


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)
=10×4.184 J
=41.84 J
