Mpemba effect - Wikipedia

The Mpemba effect is named after Tanzanian schoolboy Erasto Bartholomeo Mpemba (1950–2024) whose story of it in 1963 became highly popularized. The discovery and noted observations of it, however, originate in ancient times, having been said by Aristotle to be common knowledge. Se mer 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 … Se mer The phenomenon, when taken to mean "hot water freezes faster than cold", is difficult to reproduce or confirm because this statement is ill … Se mer While the actual occurrence of the Mpemba effect is a matter of controversy, several theoretical explanations could explain its occurrence.
