supercooling and superheating





A liquid cooled below its freezing point without the solid phase separating out is in a metastable supercooled state. Addition of a small amount of solid or shaking may cause the liquid to freeze. A liquid heating above its boiling point or a saturated vapor heated after all traces of liquid have evaporated is superheated. This state is also metastable.
