supercooled
Adjective (Physics): - "Supercooled" describes a liquid that has been cooled below its normal freezing point without solidifying. This is a metastable state where the liquid remains liquid even though it is colder than the temperature at which it would typically freeze.
- (The water was cooled below its usual freezing point but stayed liquid.)
- (Researchers examine liquids that are colder than their freezing point but not yet solid.)
- (Tiny water drops in the sky can stay liquid even when it is very cold.)
Metastable supercooled state: A condition where a liquid is thermodynamically unstable but kinetically prevented from freezing due to the absence of nucleation sites.
- The supercooled solution remained in a metastable state for several hours. (The liquid was unstable but did not freeze because no crystals started to form.)
Supercooled in everyday contexts: Often used metaphorically to describe something that is "cooled" or "chilled" to an extreme degree, though this is rare.
- His supercooled demeanor made him seem unapproachable. (His extremely cold and detached attitude.)
Supercooling (noun): The process or phenomenon of cooling a liquid below its freezing point without solidification.
- Supercooling is common in cloud physics and can lead to hail formation. (The process of creating a supercooled state.)
Supercool (verb): To cool a liquid below its freezing point without it becoming solid.
- If you supercool pure water carefully, it can remain liquid at -20°C. (To perform the action of supercooling.)
Undercooled: Another term for supercooled, especially in materials science.
- The undercooled metal alloy showed unusual properties. (The metal was cooled below its melting point without solidifying.)
Metastable liquid: A liquid in a supercooled state, emphasizing its temporary stability.
- The metastable liquid eventually crystallized when disturbed. (The supercooled liquid froze after a trigger.)
- On thin ice: While not directly about supercooling, this idiom relates to the idea of a precarious state, similar to the unstable nature of a supercooled liquid.
- The project is on thin ice, much like a supercooled liquid ready to freeze. (The project is in a delicate, unstable condition.)
- "Supercooled" is a technical term used primarily in physics, chemistry, and meteorology. It is not commonly used in everyday conversation.
- The opposite process is superheating, where a liquid is heated above its boiling point without vaporizing.
