An ice bag containing 0°C ice is much more effective in absorbing heat than one containing the same amount of 0°C water. The specific heat capacity of water is 1.00 kcal/(kg · °C), and its latent heat of fusion is 79.8 kcal/kg. (a) How much heat in kcal is required to raise the temperature of 0.740 kg of water from 0°C to 29.0°C? kcal (b) How much heat is required to first melt 0.740 kg of 0°C ice and then raise its temperature to 29.0°C? kcal
