  • Supercooling - Wikipedia
    Supercooling is the cooling of a liquid below its freezing point without it becoming solid Freezing point depression is when a solution can be cooled below the freezing point of the corresponding pure liquid due to the presence of the solute; an example of this is the freezing point depression that occurs when salt is added to pure water
  • What is supercooling and why does it happen? - ScienceOxygen
    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
  • Scientists Say: Supercool - Science News Explores
    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 of Water | Harvard Natural Sciences Lecture Demonstrations
    After the hassle of supercooling pure water in an ultra-clean ultra-smooth flask, Mother Nature knows something we don't We are sure the preparation can be simplified, but at this time we've had no success with any elements of the cooling process changed
  • Supercooling - an overview | ScienceDirect Topics
    Supercooling is an undesired property of phase change materials due to the poorly predictable occurrence of crystallization during cooling For such situations, the stored latent heat cannot be recovered which can be an issue for temperature-controlled applications
  • Science is cool. . . supercool – Science in School
    When we cool something below its freezing point, it solidifies – at least, that’s what we expect Tobias Schülli investigates why this is not always the case How is it possible that clouds at high altitude, at a temperature lower than 0 °C, consist of tiny droplets of water instead of ice?
  • Experimental explanation of supercooling : why water does not . . . - ESRF
    Supercooling, a state where liquids do not solidify even below their normal freezing point, still puzzles scientists today A good example of this phenomenon is found everyday in meteorology: clouds in high altitude are an accumulation of supercooled droplets of water below their freezing point
  • Supercooling Explained
    What is Supercooling? Supercooling is the process of lowering the temperature of a liquid below its freezing point without it becoming a solid
