Calculate the entropy change when two moles of water boil at 100.0 °C. The value
of Ava,Ħ is 40.65 kJ moll. What is the entropy change if this phase transition
occurs at 110.0 °C? Take the molar heat capacity at constant pressure of water in
the liquid phase to be 75.291 J mol K and the molar heat capacity at constant
pressure of water in the gas phase to be 33.58 J mol·' K-'.
