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. In 2024, two research groups independently and simultaneously found a theoretical Mpemba effect and … Se mer Other phenomena in which large effects may be achieved faster than small effects are: • Latent heat: Turning 0 °C (32 °F) ice to 0 °C (32 °F) water takes the same amount of energy as heating water from 0 °C (32 °F) to 80 °C (176 °F); Se mer Historical context Various effects of heat on the freezing of water were described by ancient scientists such as Aristotle: "The fact that the … Se mer The following explanations have been proposed: • Microbubble-induced heat transfer: that the process of boiling induced microbubbles in that … Se mer • Density of water • Heat capacity • Water cluster • Newton’s Law of Cooling Se mer NettetThe Mpemba effect is the phenomenon where hot water freezes quicker than cold water.
