Scientific definitions for supercool

supercool

[ sōō′pər-kōōl′ ]

To cool a substance below a phase-transition temperature without the transition occurring. For example, water can be cooled well below the freezing point without freezing (as often happens in the upper atmosphere); the introduction of an impurity or surface can then trigger freezing. Supercooling is an example of hysteresis. Compare superheat.
