The Mpemba Effect

The Mpemba Effect, or the phenomena where hot water freezes more quickly than cold water, has long captivated scientists and philosophers, and there are records of it dating back to Aristotle. Despite the fact that water is the most prevalent component on Earth, we have only witnessed it there.

The phenomena was separately observed by numerous researchers over the years, but Erasto Mpemba, a Tanzanian high school student, is credited with noticing it in a chance experiment in 1963. His physics instructor, Dr. Denis Osborn, assisted him as he continued to compose a paper outlining the effect in great detail. Numerous theories have been put up since then to explain the occurrence, but few have proven particularly successful.
