Exercise of calculating entropy

Exercise of calculating entropy.

We can calculate the entropy changes between two states of different temperature if we know the heat capacities.

When the pressure is constant, integration of Cp over temperature with respect to temperature gives the entropy changes upon temperature change within a single phase. If there is phase transition within the temperature range of interest, latent heat and the entropy change of phase transition should be considered also.
