Hot water freezes faster myth
WebAug 17, 2024 · Given that hot water is closer to boiling than cold water is, it evaporates faster. You can thank vapor pressure for that. So because hot water evaporates faster, some of the liquid becomes gaseous as the water freezes. Therefore, by the time freezing occurs in the hot/cold water samples, the hot sample will have less liquid mass. WebJul 2, 2014 · The phenomenon of hot water turning into ice faster than cold water is known as the Mpemba effect, named after a Tanzanian student who observed his hot ice cream mix freezing more rapidly than the cold version. Separating homemade ice cream into ice cube trays also speeds up freezing. Image by J. Kenji Lopez-Alt/ Serious Eats.

WebApr 22, 2024 · Why does hot water freeze faster than cold water? 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.
