Ethylene :: Ethylene (n.) A colorless, gaseous hydrocarbon, C2H4, forming an important ingredient of illuminating gas, and also obtained by the action of concentrated sulphuric acid in alcohol. It is an unsaturated compound and combines directly with chlorine and bromine to form oily liquids (Dutch liquid), -- hence called olefiant gas. Called also ethene, elayl, and formerly, bicarbureted hydrogen..

Fluorine :: Fluorine (n.) A non-metallic, gaseous element, strongly acid or negative, or associated with chlorine, bromine, and iodine, in the halogen group of which it is the first member. It always occurs combined, is very active chemically, and possesses such an avidity for most elements, and silicon especially, that it can neither be prepared nor kept in glass vessels. If set free it immediately attacks the containing material, so that it was not isolated until 1886. It is a pungent, corrosive, colorles

Trimethylene :: Trimethylene (n.) A gaseous hydrocarbon, C3H6, isomeric with propylene and obtained from it indirectly. It is the base of a series of compounds analogous to the aromatic hydrocarbons..

Gasiform :: Gasiform (a.) Having a form of gas; gaseous.

Fluid :: Fluid (a.) Having particles which easily move and change their relative position without a separation of the mass, and which easily yield to pressure; capable of flowing; liquid or gaseous..

Helium :: Helium (n.) A gaseous element found in the atmospheres of the sun and earth and in some rare minerals.

Ethane :: Ethane (n.) A gaseous hydrocarbon, C2H6, forming a constituent of ordinary illuminating gas. It is the second member of the paraffin series, and its most important derivatives are common alcohol, aldehyde, ether, and acetic acid. Called also dimethyl..

Propane :: Propane (n.) A heavy gaseous hydrocarbon, C3H8, of the paraffin series, occurring naturally dissolved in crude petroleum, and also made artificially; -- called also propyl hydride..

Eructation :: Eructation (n.) A violent belching out or emitting, as of gaseous or other matter from the crater of a volcano, geyser, etc..

Dissociation :: Dissociation (n.) The process by which a compound body breaks up into simpler constituents; -- said particularly of the action of heat on gaseous or volatile substances; as, the dissociation of the sulphur molecules; the dissociation of ammonium chloride into hydrochloric acid and ammonia..

Vapor :: Vapor (n.) Any substance in the gaseous, or aeriform, state, the condition of which is ordinarily that of a liquid or solid..

Nebula :: Nebula (n.) A faint, cloudlike, self-luminous mass of matter situated beyond the solar system among the stars. True nebulae are gaseous; but very distant star clusters often appear like them in the telescope..

Oxygen :: Oxygen (n.) A colorless, tasteless, odorless, gaseous element occurring in the free state in the atmosphere, of which it forms about 23 per cent by weight and about 21 per cent by volume, being slightly heavier than nitrogen. Symbol O. Atomic weight 15.96..

Methane :: Methane (n.) A light, colorless, gaseous, inflammable hydrocarbon, CH4; marsh gas. See Marsh gas, under Gas..

Butylene :: Butylene (n.) Any one of three metameric hydrocarbons, C4H8, of the ethylene series. They are gaseous or easily liquefiable..

Propylene :: Propylene (n.) A colorless gaseous hydrocarbon (C3H6) of the ethylene series, having a garlic odor. It occurs in coal gas, and is produced artificially in various ways. Called also propene..
