Why do the hot water pipes freeze first?
Known as the Mpemba effect, water behaves unlike most other liquids by freezing into a solid more rapidly from a heated state than from room temperature.

Known as the Mpemba effect, water behaves unlike most other liquids by freezing into a solid more rapidly from a heated state than from room temperature. The Mpemba effect is named after a Tanzanian student called Erasto Mpemba, who observed that hot ice cream mix froze before the cold mix.Click to see full answer. Consequently, why do hot water pipes freeze before cold?The Mpemba effect is the observation that warm water freezes more quickly than cold water. Hence the faster freezing. Another is that warm water evaporates rapidly and since this is an endothermic process, it cools the water making it freeze more quickly.Also Know, does hot water freeze faster than cold water Mythbusters? Hot water freezes faster than cold, known as the Mpemba effect. Evaporation is the strongest candidate to explain the Mpemba effect. As hot water placed in an open container begins to cool, the overall mass decreases as some of the water evaporates. With less water to freeze, the process can take less time. In this regard, how do I keep my hot water pipes from freezing? A trickle of hot and cold water might be all it takes to keep your pipes from freezing. Let warm water drip overnight, preferably from a faucet on an outside wall. Keep your thermostat set at the same temperature during both day and night.Does hot water freeze first?Evaporation. One explanation of the effect is that as the hot water cools, it loses mass to evaporation. With less mass, the liquid has to lose less heat to cool, and so it cools faster. With this explanation, the hot water freezes first, but only because there’s less of it to freeze.
