Suppose you want to raise the temperature of a mass m of ice from T0< 0 °C to T > 100 °C. In this problem, represent the heat of fusion as Lf, the heat of vaporization as Lv, and the temperatures at which the phase changes occur as Tf and Tv. How much heat, in kilocalories, must be transferred for this to happen to 0.195kg of ice starting at a temperature of -20 C and ending at a temperature of 130 C?  How much time, in seconds, is required to do this, assuming a constant 20.0kJ/s rate of heat transfer?
