Suppose you want to raise the temperature of a mass m of icefrom T0 < 0 °C to T > 100 °C. In this problem, represent theheat of fusion as Lf, the heat of vaporization as Lv, and thetemperatures at which the phase changes occur as Tf and Tv
a)How much heat must be transferred for this to happen,including the energy needed for phase changes? Your answer shouldbe in terms of the variables in the introduction and the specificheats of ice (ci), water (cw), and steam (cs). The latent heats areLf = 334 kJ/kg and Lv = 2256 kJ/kg
b)How much heat, in kilocalories, must be transferred for thisto happen to 0.185 kg of ice starting at a temperature of -20 °Cand ending at a temperature of 130 °C?
c) How much time, in seconds, is required to do this, assuming aconstant 20.0 kJ/s rate of heat transfer?
