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:
For an ideal gas, the difference between these two is CP – CV = nR, the universal gas constant and where n= no. of moles
Hence for 10 moles of an ideal gas CP – CV = 10 R
CP – CV = 10 × 8.314 J
= 83.14 J
