Calculate the difference in molar entropy (a) between ice and liquid water at 5.00 °C, and (b) between liquid water and its vapor at 90.0 °C and 1.00 atm. The differences in molar heat capacities on melting and on vaporization are 37.3 and -41.9 J•mol ^-1 *K^-1, respectively. Distinguish between the entropy changes of the sample (system), surroundings, and the total system (universe), and discuss the spontaneity of the transitions at the two temperatures. Note that the final answers are really looking for the entropy change of the universe.
