To convert 1.00 kg of ice at 0°C to steam at 100°C, you need to account for the heat required to melt the ice, heat the water to 100°C, and then convert it to steam. The total heat is the sum of the heat of fusion (80 kcal/kg), the heat to raise the temperature of water (100 kcal/kg), and the heat of vaporization (540 kcal/kg), totaling 720 kcal.
