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