(a) How much heat transfer (in kJ) is necessary to raise the temperature of a 0.250 kg piece of ice from 22.0C to 132C, including the energy needed for phase changes? (Assume the substance remains at a constant volume throughout each stage of the heating process. The latent heat of fusion is 334 kJ/kg. The latent heat of vaporization is 2256 kJ/kg.)

(b) How much time (in s) is required for each stage, assuming a constant 20.5 kJ/s rate of heat transfer? (Enter your answers as a comma-separated list. Enter your times in order from the earliest stage to the final stage of the heating process.)

(c) Make a graph of temperature versus time for this process.
