- To supercool a liquid means to chill it below its freezing point without it turning solid. Supercooling can happen because liquids are loose jumbles of atoms. It’s hard for such disordered atoms to lock themselves into the crystal structure of a solid. Liquids often need tiny bits of solid matter to get them started.

Supercooling, [1] also known as undercooling, [2] [3] is the process of lowering the temperature of a liquid below its freezing point without it becoming a solid.
Explore what happens when a liquid is supercooled using sodium thiosulfate in this class practical. In this experiment, students melt sodium thiosulfate crystals, before cooling them to a state well below the melting point. The melt now exists in a metastable supercooled state.
Insulated gloves ensure protection from extreme cold temperatures. Everything you need to know about Super Cooling for the Level 3 Applied Science BTEC exam, totally free, with assessment questions, text & videos.
Sep 4, 2022 · Supercooling, also known as undercooling, is the process of lowering the temperature of a liquid or a gas below its freezing point without it becoming a solid. It achieves this in the absence of a seed crystal or nucleus around which a crystal structure can form.
In traditional polymer science, the word “supercooling” refers to the difference in temperature from the equilibrium melting temperature (Tm°) to any isothermal temperature below Tm° where crystallization can occur.
Oct 9, 2023 · Supercool (verb, “SOOP-er-kool”) To supercool a liquid means to chill it below its freezing point without it turning solid. Supercooling can happen because liquids are loose jumbles of atoms. It’s hard for such disordered atoms to lock themselves into the crystal structure of a solid.
Supercooling of Water. Pure water cooled to below 273K without freezing; seeded to spontaneously crystallize. What it shows: A liquid can be taken to a temperature below its freezing point if it is cooled slowly and there are no nucleation sites for crystallization to begin.
