DOES HOT WATER TURN INTO ICE FASTER THAN COLD WATER?


The Mpemba effect is the theory that warmer water can freeze faster than colder water. The effect has been noted since ancient times but scientists have struggled to explain why it occurs. Hydrogen bonds bring individual water molecules into close contact, which triggers natural repulsion between the water molecules and causes the bonds between oxygen and hydrogen atoms to stretch as well as store energy.
So as the liquid warms, it makes the water molecules sit further apart from each other as the hydrogen bonds stretch. When the molecules shrink again and give up their energy, this results in it cooling, which the scientists say means that warm water cools faster than cold water and explains the Mpemba effect.
