(a) How much heat transfer (in kJ) is necessary to raise the temperature of a 0.250 kg piece of ice from -24.0°C to 132°C, including the energy needed for phase changes? (Assume the substance remains at a constant volume throughout each stage of the heating process.) 776.8 kJ (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.) t = S
