"Supercooling" refers to a phenomenon where a liquid is cooled below its freezing point without actually turning into a solid. This term can be difficult to grasp, but fortunately, there are many synonyms that can be used to describe this process. Alternative words for supercooling include undercooling, subcooling, and hypothermic melting. Each of these terms helps to convey the idea of liquids being exposed to temperatures below their natural freezing points, but retaining their liquid form. Regardless of which word you choose to use, they all share the same concept of a liquid remaining liquid below its freezing point, which can lead to interesting scientific discoveries.
