100 g of ice at 0 C is melted, heated to 100 C and vaporized at that temperature. These changes are brought about by a heater that supplies heat at a constant rate of 1000 W. Sketch graphs showing a) the temperature vs. time b) the enthalpy vs. time c) Enthalpy vs. temperature for this process. Mark the salient features.

Process occurs at constant pressure of 1 bar. Assume that heat capacity of the liquid remains constant in the temperature range explored.
