一個關於材料科學的問題!!!請高手幫我的忙!!!

In physics, superheating (sometimes referred to as boiling retardation, or boiling delay) is the phenomenon in which a liquid is heated to a temperature higher than its standard boiling point, without actually boiling. This can be caused by rapidly heating a homogeneous substance while leaving it undisturbed (in order to avoid the introduction of bubbles at nucleation sites).

Supercooling is the process of chilling a liquid below its freezing point, without it becoming solid.
