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.

The effect of loneliness on health drove the WHO last week to announce its plans to launch a commission with a diverse set of health leaders to combat social isolation.
Scrolling on social media is also a way to "disassociate" and give the brain a rest after a long day, Bobinet said. This is an "avoidance behavior," which the habenula controls.
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 ...
