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 must be transferred for this to happen, including the energy needed for phase changes? Your answer should be in terms of the variables in the introduction and the specific heats of ice (ci), water (cw), and steam (cs). The talent heats are Lf= 334kJ/kg and Lv=2256kJ/kg?
