what is the exact meaning of “supercooling”?
is “supercooling” a process that changes substances from liquid to solid, or from gases to solid?

Supercooling is the process of chilling a liquid below its freezing point, without it becoming solid.

Supercooling has to do with the rate at which things are cooled, not between which states. Although, most supercooling will occur with a substance in its liquid form. But rather than it becoming a solid, the sheer speed at which it is cooled will cause it to become little crystals or “nucleations.”
Hope this helps.

Supercooling is the process of chilling a liquid below its freezing point, without it becoming solid.
A liquid below its freezing point will crystallize in the presence of a seed crystal or nucleus around which a crystal structure can form. However, lacking any such nucleus, the liquid phase can be maintained all the way down to the temperature at which crystal homogeneous nucleation occurs. The homogeneous nucleation can occur above the glass transition where the system is an amorphous—that is, non-crystalline—solid.

Cooling of a liquid below its freezing point without freezing taking place; or the cooling of a saturated solution without crystallization taking place, to form a supersaturated solution. In both cases supercooling is possible because of the lack of solid particles around which crystals can form. Crystallization rapidly follows the introduction of a small crystal (seed) or agitation of the supercooled solution

Basically the cooling of a liquid below its freezing point without freezing taking place.
Google “supercooling”. You’ll find lots of info.

super cooling, it’s cooling strongly
