(a) How much heat transfer is necessary to raise the temperature of a 0.200-kg piece of ice from −20.0ºC to 130ºC, including the energy needed for phase changes? (b) How much time is required for each stage, assuming a constant 20.0 kJ/s rate of heat transfer? (c) Make a graph of temperature versus time for this process. Note: Ice’s specific heat is 2090 J/(kg⋅ºC) and latent heat for water at 0ºC is 334kJ/kg.
