(a) how much heat transfer (in kj) is necessary to raise the temperature of a 0.190 kg piece of ice from −18.0°c to 134°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 19.0 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.)
