It must be cooled to 0 oC.
Hot water freezes faster
Hot Water
The process of water freezing into ice involves the temperature of water being lowered to 32 degrees Celsius. Hot water will take longer to freeze because the difference between the temperature of hot water and 32 degrees is greater than the temperature of cold water and 32 degrees.
hot filtered water
No hot water freezes, it has to cool off first.
It has been proven that hot water freezes faster than cold water.
water, it freezes when it is cold and turns to steam when it is hot.
is when hot water freezes faster then colder water (or other liquids)
If you mean, compared with cold water, it doesn't. Hot water has to cool down first, before it freezes.
discovered that hot water freezes earliar than cold water.
Usually not, but it is known that in some very special cases, hot water freezes faster.
I believe hot water freezes faster because it is supercooled. Cold water is non-supercooled. When cold water freezes ice crystals form and float to the top, forming a layer of ice over the top of the water, so the layer of ice stops evaporation . While the hot water, which is probably no longer hot in the freezer,when it does freeze, it freezes throughout, creating more or less of a slush before freezing solid.
