. 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 JK-¹mol-¹ and 41.9 JK-¹mol-¹, 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.
