Section 2.10
Read/skip
Section 2.11: Heat Capacity
- - CV,m - molar heat capacity at constant volume.
- - CP,m - molar heat capacity at constant pressure.
- heat capacities are usually temperature dependent, so CV,m(T) and CP,m(T); more later in Ch 3.
- - See Table 2.5: Molar Heat Capacity, CP,m(T), of Gases (298-800K), page 629.

Relationship between CV,m and CP,m...
- CP - CV = nR
- CP,m - CV,m = R
