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.
Q. What is supercooling and why does it occur?
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.

Q. Why does supercooling occur experimentally?
Experimental explanation of supercooling: Why water does not freeze in the clouds. Supercooled liquids are trapped in a metastable state even well below their freezing point, which can only be achieved in liquids that do not contain seeds that may trigger crystallization.
Q. When cooling a solution what is supercooling?
Supercooling is when a substance is temporarily cooled below its freezing point without becoming a solid. This occurs when heat is removed from a liquid so rapidly that the molecules do not have enough time to align themselves in the ordered structure of a solid. Supercooling is also called as undercooling.
Q. How can we prevent supercooling?
Several freezing procedures were tried to prevent supercooling. Forsythiarootsectionspartiallyimbeddedinicedidnotsupercool,but sections frozen in air in moist greenhouse soil, or wrapped in moist tissue paper supercooled to -2 to -6oC before freezing.
Q. What are examples of supercooled liquids?
Supercooling is the process of chilling a liquid below its freezing point, without it becoming solid. A super-cooled liquid is a liquid below its freezing point that has not crystalized to freeze. Glass is an example of supercooled liquid.
Q. Which is called supercooled liquid?
Glass is called supercooled liquid because glass is an amorphous solid. Amorphous solids have the tendency to flow but, slowly. It does not form a crystalline solid structure as particles in solids do not move but here it moves. Hence it is called a supercooled liquid.
Q. How do you make supercooled liquids?
The simplest way to supercool water is to chill it in the freezer.
- Place an unopened bottle of distilled or purified water (e.g., created by reverse osmosis) in the freezer.
- Allow the bottle of water to chill, undisturbed, for about 2-1/2 hours.
- Carefully remove the supercooled water from the freezer.
Q. Which of the following is a supercooled liquid?
Glass is sometimes called a supercooled liquid because it does not form a crystalline structure, but instead forms an amorphous solid that allows molecules in the material to continue to move.
