Calculate the change in entropy of 144 g ice at -5 oC as it is heated to 0 oC , melted, heated to 100 oC, and then vaporized at that temperature. Suppose that the changes are brought by a heater that supplies energy at constant rate, and sketch a graph showing (a) the change in temperature of the system, (b) the enthalpy of the system, and (c) the entropy of the system as a function of time.
