(a)

How much heat transfer (in kJ) is necessary to raise the temperature of a 0.170 kg piece of ice from −18.0°C to 124°C, including the energy needed for phase changes? (Assume the substance remains at a constant volume throughout each stage of the heating process.)

(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.)
