The quantity of heat *Q* that changes the temperature *T* of a mass *m* of a substance is given by *Q* = *mc**T*, where *c* is the specific heat capacity of the substance. For example, for H20, *c* = 1 cal/g°C. And for a change of phase the quantity of heat *Q* that changes the phase of a mass *m* is *Q* = *mL*, where *L* is the heat of fusion or heat of vaporization of the substance. For example, for H20 the heat of fusion is 80 cal/g or 80 kcal/kg, and the heat of vaporization is 540 cal/g or 540 kcal/kg. Use these relationships to determine the number of calories to change(a) 0.6 kg of 0°C ice to 0.6 kg 0°C ice water
