The difference between CPand CV can be derived using the empirical relation H = U + PV. Calculate the difference between CP and CV for 10 mole of an ideal gas.
o CP is the heat capacity at constant pressure and CV is the heat capacity at constant volume.
o For an ideal gas, the difference between these two is CP - CV = nR, the universal gas constant and where n= no. Of moles.
o Hence for 10 moles of an ideal gas CP - CV = 10 R
= 10 × 8.314 J
= 83.14 J
