Energy can be removed from water as heat at and even below the normal freezing point
Chapter 20, Problem 21(choose chapter or problem)
Energy can be removed from water as heat at and even below the normal freezing point (0.0 C at atmospheric pressure) without causing the water to freeze; the water is then said to be supercooled. Suppose a 1.00 g water drop is supercooled until its temperature is that of the surrounding air, which is at 5.00C. The drop then suddenly and irreversibly freezes, transferring energy to the air as heat. What is the entropy change for the drop? (Hint: Use a three-step reversible process as if the water were taken through the normal freezing point.) The specific heat of ice is 2220 J/kg K.
