An aeriform fluid; -- a term used at first by chemists as synonymous with air, but since restricted to fluids supposed to be permanently elastic, as oxygen, hydrogen, etc., in distinction from vapors, as steam, which become liquid on a reduction of temperature. In present usage, since all of the supposed permanent gases have been liquified by cold and pressure, the term has resumed nearly its original signification, and is applied to any substance in the elastic or aeriform state.

A complex mixture of gases, of which the most important constituents are marsh gas, olefiant gas, and hydrogen, artificially produced by the destructive distillation of gas coal, or sometimes of peat, wood, oil, resin, etc. It gives a brilliant light when burned, and is the common gas used for illuminating purposes.

Laughing gas.

Any irrespirable aeriform fluid.

To singe, as in a gas flame, so as to remove loose fibers; as, to gas thread.

To impregnate with gas; as, to gas lime with chlorine in the manufacture of bleaching powder.

to expose to a poisonous or noxious gas

An aeriform fluid; - a term used at first by chemists as synonymous with air, but since restricted to fluids supposed to be permanently elastic, as oxygen, hydrogen, etc.

Elastic, airlike fluid; a thin, airlike mixture obtained from minerals and used to give light and heat; an airlike mixture of chemicals, poisonous to inhale; colloquially, gasoline.

To cause to inhale poison gas; a method of warfare in troduced by the Germans in the World War.

Gassed.

Gassing.

A thin fluid, like air, capable of indefinite expansion, but usually convertible by compression and cold into a liquid.

Aeriform matter.

In popular language, coal gas: in chem. an elastic aeriform fluid, a term originally synonymous with air, but afterwards restricted to such bodies as were supposed to be incapable of being reduced to a liquid or solid state. Under this supposition gas was defined to be "a term applied to all permanently elastic fluids or airs differing from common air." Since the liquefaction of gases by Faraday, effected by combining the condensing powers of mechanical compression with that of very considerable depression of temperature, the distinction between gas and vapor, viz., that the latter could be reduced to a liquid or solid condition by reduction of temperature and increase of pressure, while gas could not be so altered, is no longer tenable, so that the term has resumed nearly its original signification, and designates any substance in an elastic aeriform state. Gas may now be defined to be a substance possessing the condition of perfect fluid elasticity, and presenting, under a constant pressure, a uniform state of expansion for equal increments of temperature, being distinguished by this last property from vapor, which does not present such a rate of uniform expansion. Gases are distinguished from liquids by the name of elastic fluids; while liquids are termed non-elastic because they have, comparatively, no elasticity. But the most prominent distinction is the following: -Liquids are compressible to a certain degree, and expand into their former state when the pressure is removed; and in so far they are elastic, but gases appear to be in a continued state of compression, for when left unconfined they expand in every direction to an extent which has not hitherto been determined.

Any fluid in the form of air. esp. that prepared from coal and used for lighting.

An aeriform elastic fluid; such a fluid used for lighting or heating.

A single jet or fiame supplied by gas.

Gasoline. gasjet; gaslight.

An elastic fluid in the form of air; popularly that obtained from coal, and used for purposes of lighting.

An aeriform fluid; any air; the air or carburetted hydrogen used to light our houses.

An elastic aeriform fluid.

That form of matter in which particles tend continually to diverge from each other, so that the body itself tends constantly to increase in volume in all directions and fills the whole of the vessel in which it is contained. The term, without qualification, denotes, in common parlance, illuminating gas.
