...continue with Sec 5.7, Absolute Entropy (Figures 5.7, 5.8, 5.9)

Example problem 5.7...see figure 5.7... partial class notes

- 3 solid heat capacities that are all a function of T, (note Solid III has 2 heat capacity ranges - 4 total terms),
- like other phase transitions there is a ΔH associated with each of these solid phase changes (2 phase changes total),
- heat of fusion...ΔHfus @ 54.39 K
- 1 heat capacity associated with liquid that is a function of T,
- heat of vaporization...ΔHvap @ 90.20 K
- 1 heat capacity associated with gas that is a function of T.

TOTAL of 10 terms.
