Calculate the change in entropy of the system when 10.0 g of ice at −10.0 °C is converted into water vapour at 115.0 °C and at a constant pressure of 1 bar. The molar constant-pressure heat capacities are: Cp, m(H2O(s)) = 37.6 J K−1 mol−1; Cp, m(H2O(l)) = 75.3 J K−1 mol−1; and Cp, m(H2O(g)) = 33.6 J K−1 mol−1. The standard enthalpy of vaporization of H2O(l) is 40.7 kJ mol−1, and the standard enthalpy of fusion of H2O(l) is 6.01 kJ mol−1, both at the relevant transition temperatures.
