What about when the liquid water freezes and expands into ice?
Does the exothermic energy needed to melt ice to water = the exothermic energy released when that same water freezes to ice? If so, how do you maintain conservation of energy when their is additional mechanical work being done when...
Where does the Kinetic energy of the expansion of freezing ice come from? For example, say you had a gram of water inside a piston. The water freezes and the expansion of ice pushes the piston up. Since the heat of fusion of water is 80 calories per gram, let's say to initally melt that ice to...
