When water freezes, the molecules slow down and assume a fixed position, although not quite in the way that one might think. Water is made of molecules with two hydrogen atoms and an oxygen atom, but those molecules don'...

Fresh water freezes at 32 degrees Fahrenheit, which is 0 degrees Celsius and 273.15 degrees on the Kelvin scale. Seawater freezes at a slightly lower temperature than fresh water due to its high salt content.

Hot water sometimes freezes faster than cold water, but there is no definitive answer as to why this occurs. Scientists believe many factors may play a role, such as evaporation, supercooling and dissolved gases.
