Definitions for "Supercooled"
Liquid water droplets between 0 and -40 degrees Celsius that would freeze immediately if particles were present to start the solidifying process.
Water that remains liquid when cooled below the freezing point is said to be supercooled. Tiny droplets, such as those that make up clouds, are much more easily supercooled than larger masses of water.
the condition when a liquid remains in the liquid state even through its temperature is below its freezing point
