Adiabatic Ad`i*a*bat"ic, a. [Gr. ? not passable; 'a priv. + ? through + ? to go.] (Physics) Not giving out or receiving heat. -- {Ad`i*a*bat`ic*al*ly}, adv. [Webster 1913 Suppl.]

Note: The adiabatic expansion of carbon dioxide from a compressed container causes the temperature of the gas to decrease rapidly below its freezing point, resulting in the familiar carbon dioxide ``snow'' emitted by carbon dioxide fire extinguishers. [PJC.]

{Adiabatic line} or {curve}, a curve exhibiting the variations of pressure and volume of a fluid when it expands without either receiving or giving out heat. --Rankine. [1913 Webster]
