Mpemba Effect is such a shocking and somewhat mysterious scientific phenomenon, which shows that hot water can turn into ice faster than cold water. In general our idea, the colder an object, the faster it turns into ice. But in 1963 Tanzanian student Erasto Mpemba noticed this unusual incident first. He noticed, hot milk or water kept in the same environment is freezing faster than cold milk or water. Later scientists started researching this and the incident is named "Mpemba Effect".
The effect is yet to be fully explained, but scientists have mentioned some possible reasons.
First of all, evaporation (Evaporation): Steam comes out of hot water quickly, resulting in water levels and the remaining water cools easily.
Secondly, Convection (Convection): A temperature difference in hot water causes tornado inside, accelerating the cooling process.
Thirdly, Supercooling: Cold water often remains liquid at lower temperatures without turning into ice, but hot water can freeze directly without getting into this.
Also, disolved gases vary in hot and cold water, which can affect the frozen process.
For all these reasons scientists have yet to agree with a single explanation. Yet, the Mpemba Effect is considered an interesting and researchable mystery in the world of science.
