Hot water freezes faster
The Mpemba effect is the name given to the observation that a liquid (typically water) which is initially hot can freeze faster than the same liquid which begins cold, under otherwise similar conditions. There is disagreement about its theoretical basis and the parameters required to produce the effect. The Mpemba effect is … See more The phenomenon, when taken to mean "hot water freezes faster than cold", is difficult to reproduce or confirm because this statement is ill-defined.

WebNov 4, 2013 · As the water is cooled, the bonds relax and release energy at a rate exponentially dependent upon the amount of energy stored, so that hot water releases energy faster than cold water and therefore freezes more quickly. The effect may be more complex than that, however, as previous work has suggested that convection currents … WebJan 25, 2024 · This was the first published peer-reviewed study to demonstrate the phenomenon. In the past, philosophers such as Aristotle and Sir Frances Bacon noted that hot-water froze faster than icy-cold-water. As a result, hot-water-freezes-faster-than-cold water.
