Question: Calculate the difference in molar entropy (a) between liquid water and ice at -5C, (b) between liquid water and its vapour at 95C and 1.00

Calculate the difference in molar entropy

(a) between liquid water and ice at -5°C,

(b) between liquid water and its vapour at 95°C and 1.00 atm. The differences in heat capacities on melting and on vaporization are 37.3 T K-1 rnol " and -41.9 T K-I mol:", respectively. Distinguish between the entropy changes of the sample, the surroundings, and the total system, and discuss the spontaneity of the transitions at the two temperatures.
