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]
