Super Cooling
When a liquid is cooled gently, it is found experimentally that the liquid may cool even several degrees below its freezing point without solidification. Such a liquid at a temperature below its freezing point is called super cool liquid.
Relegation: The phenomenon of melting of ice due to compression and freezing after removal of applied pressure is called relegation.
