Calculate the change in entropy of 100 g of ice at 0°C as it is melted, heated to 100°C, and then vaporized at that temperature. Suppose that the changes are brought about by a heater that supplies energy at a constant rate. Sketch a graph showing: (a) the change in temperature of the system, (b) the enthalpy of the system (c) the entropy of the system as a function of time.
