Questions
Which has more heat: 1 g ice at 0℃ or 1g water 0℃? Give reason.
Which will contain more heat energy 1 g of ice at 0°C or 1 g water at 0°C?
Solution 1
1 g of water at 0°C has more heat than 1 g of ice at 0°C. This is because ice at 0°C absorbs 360 J of heat energy to convert into water at 0°C.
Solution 2
At 0°C, 336 J of heat energy is taken in by ice, turning it into water. Water therefore has higher heat energy at 0°C.
