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