The fact that near boiling water cools down quicker than warm water used to be a well-known kitchen knowledge bit. Like my grandma who wasn't a physicist at all knew it. I guess in some places (particularly those where people microwave water) that part of culture is lost cause there's at least a whole generation which hasn't done cooking.
- teaearlgraycold 7mo agoI remember mentioning this to my high school chemistry teacher and was told I was wrong. I think I even lost points on a test.
- chotmat 7mo agoIt's because you was wrong (or at least not correct). The Mpemba Effect wasn't scientifically proven, and can be explained away with error in measurement. https://www.youtube.com/watch?v=SkH2iX0rx8U https://www.youtube.com/watch?v=SkH2iX0rx8U
- shakna 7mo agoThat video is also, outdated. A reliable way of reproducing the effect was found in 2021. [0] Though the precise cause is still unknown. [0] https://doi.org/10.1038/s42254-021-00349-8 https://doi.org/10.1038/s42254-021-00349-8
- chotmat 7mo agoThen I was wrong, at least until further research into the topic. Such is the tale of science.

- blharr 7mo agoWhat is meant by "cools down quicker"? Will near-boiling water drop 10 temperature points in a shorter time than the warm water? Yes. Will it reach 10C faster than the warm water? No.
