Supercooling

Supercooling is the process of cooling a liquid below its freezing point without it becoming a solid. This can occur when the liquid is cooled very quickly or when it is very pure and free of nucleation sites where crystals can form. It is a phenomenon that defies the normal freezing behavior of liquids.

Causes of Supercooling

Supercooling can be caused by rapid cooling, as well as by removing impurities and nucleation sites from the liquid. Without these impurities, the liquid can remain in a liquid state even at temperatures below its freezing point.

Applications of Supercooling

Supercooling has applications in various fields such as cryogenics, food preservation, and the study of phase transitions. Understanding supercooling can lead to better preservation techniques for perishable goods and improved knowledge of the behavior of liquids at low temperatures.
