WebNov 6, 2024 · When 506 of liquid water freezes, it releases 169 kJ of energy. What is freezing? Freezing, also known as solidification, is a phase transition where a liquid turns into a solid when its temperature is lowered below its freezing point. When water loses energy in the form of heat, it freezes. WebFor water at its normal freezing point of 0 ºC, the specific heat of Fusion is 334 J g -1. This means that to convert 1 g of ice at 0 ºC to 1 g of water at 0 ºC, 334 J of heat must be …
