An ice bag containing 0°C ice is much more effective in absorbing heat than one containing the same amount of 0°C water.
(a) How much heat in kcal is required to raise the temperature of 0.700 kg of water from 0°C to 27.0°C?
(b) How much heat is required to first melt 0.700 kg of 0°C ice and then raise its temperature?
(c) Explain how your answers support the contention that the ice is more effective.
