1.5 Exercise 17

A bag containing $0 ° \text{C}$ ice is much more effective in absorbing energy than one containing the same amount of $0 ° \text{C}$ water. (a) How much heat transfer is necessary to raise the temperature of 0.800 kg of water from $0 ° \text{C}$ to $30.0 ° \text{C}$? (b) How much heat transfer is required to first melt 0.800 kg of $0 ° \text{C}$ ice and then raise its temperature to $30.0 ° \text{C}$? (c) Explain how your answer supports the contention that the ice is more effective.
