Gases

A substance possessing perfect molecular mobility and the property of indefinite expansion, as opposed to a solid or liquid; any such fluid or mixture of fluids other than air. Normally, these formless substances completely fill the space, and take the shape of, their container.

List of gases

• sodium chloride - a white crystalline solid consisting mainly of sodium chloride (nacl)
• cryofluorane
• dichlorodifluoromethane
• trichlorofluoromethane
• dimethyl ether
• helium - a very light colorless element that is one of the six inert gasses; the most difficult gas to liquefy; occurs in economically extractable amounts in certain natural gases (as those found in texas and kansas)
• chlorodifluoroethane
• chlorodifluoromethane
• apaflurane
• difluoroethane
• norflurane
• hydrogen sulfide - a sulfide having the unpleasant smell of rotten eggs
• isobutane
• nitrogen - a common nonmetallic element that is normally a colorless odorless tasteless inert diatomic gas; constitutes 78 percent of the atmosphere by volume; a constituent of all living tissues
• oxygen - a nonmetallic bivalent element that is normally a colorless odorless tasteless nonflammable diatomic gas; constitutes 21 percent of the atmosphere by volume; the most abundant element in the earth's crust
• propane - colorless gas found in natural gas and petroleum; used as a fuel.
