critical temperature

n.
1. The temperature above which a gas cannot be liquefied, regardless of the pressure applied.
2. The temperature at which a material becomes a superconductor.
3. The temperature at which a property of a material, such as its magnetism, changes.

critical temperature

n
(General Physics) the temperature of a substance in its critical state. A gas can only be liquefied by pressure alone at temperatures below its critical temperature
