The Mpemba effect is the name given to the observation that a liquid (typically water) that 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.
Erasto Bartholomeo Mpemba [1] (1950–2023) [note 1] was a Tanzanian game warden who, as a schoolboy, discovered the eponymously named Mpemba effect, a paradoxical phenomenon in which hot water freezes faster than cold water under certain conditions; this effect had been observed previously by Aristotle, Francis Bacon, and René Descartes.
Mpemba was a confederation in the western Congo Basin, at least from the 13th century. Its northernmost territory, Mpemba Kasi, was incorporated into the founding of the Kingdom of Kongo in the 14th century, and it was conquered. It neighboured the confederations of Vungu and Seven Kingdoms of Kongo dia Nlaza.
These are the most vocal of bears, with the exception of the giant panda. They make noises that are decidedly not expected of bears. You can recognize an Andean bear by the soft, purring sound and ...
The 'recent view of the Mpemba effect' was put in as balance as recent papers still remain undecided over the reason for the Mpemba effect, at least there is no consensus in the recent scientific literature; the reasons still being given are in the 'Causes' section of the article.
To get those answers, two autopsies would be performed: one, two days after Melissa's death, and then another, about two weeks later while lab work was completed. The results: normal carbon ...
I don't know about you, Pandas, but I love period dramas. They're like a window into the past: we can see how people looked and lived a hundred or even more years ago.However, they're often just ...
The Mpemba Effect relates to hot water freezing faster than cold water in certain circumstances, none of which is identified as having been thrown up in the air. Also, while the Mpemba Effect is not well understood, the trick of throwing hot water into very cold air so that it quickly vaporizes and then condenses into small droplets and freezes ...
