alijäähtyminen
Alijäähtyminen, also known as supercooling, is a phenomenon where a liquid is cooled below its freezing point without solidifying. This state is metastable, meaning the liquid is unstable and can transition to a solid state if disturbed. The absence of nucleation sites, such as impurities or rough surfaces, is crucial for preventing crystallization in a supercooled liquid.
When a supercooled liquid is agitated or exposed to a seed crystal, it can rapidly solidify. This
This phenomenon has practical implications in meteorology, where supercooled water droplets in clouds can contribute to
