A colorless, odorless gas that forms from incomplete combustion of an organic fuel. Carbon monoxide is poisonous to human and animal life.
Industry:Aviation
A colorless, odorless, and tasteless gas that is about 1.5 times as heavy as air. Carbon dioxide, composed of one atom of carbon and two atoms of oxygen, makes up about five hundredths of one percent of the air we breathe. Green plants take in carbon dioxide and combine it with water to make sugar. Humans and animals give off carbon dioxide in their exhaled breath.
Even though carbon dioxide makes up only an extremely small part of the air we breathe, it is necessary, because it helps control our rate of breathing. Carbon dioxide is important commercially because of its use as a fire extinguishing agent.
Industry:Aviation
A colorless, odorless, inert, gaseous chemical element. Argon has an atomic number of 18 and an atomic weight of 39.998. The symbol for argon is Ar.
Argon is commonly used to fill electric light bulbs and the envelopes of electron tubes. The argon takes the place of air, which contains oxygen, and by keeping oxygen away from the hot filaments in the bulbs and tubes, the filaments will not burn out, or oxidize.
Industry:Aviation
A colorless, odorless, tasteless, gaseous chemical element that makes up about 21% of the earth’s atmosphere. Oxygen’s symbol is O, its atomic number is 8, and its atomic weight is 15.9994. Oxygen will not burn, but it supports combustion and combines chemically with all other elements except the inert gases. Oxygen is absolutely necessary to support human and animal life.
Industry:Aviation
A colorless, odorless, tasteless, inert gaseous chemical element. Helium’s symbol is He, its atomic number is 2, and its atomic weight is 4.0026. Because helium will not combine with other chemical elements, it is used to force oxygen away from the molten metal in certain types of arc welding, and to fill some types of electron tubes to prevent oxygen from contacting the hot filaments.
Because of its lightness and because it will not burn, helium is used to inflate lighter-than-air aircraft.
Industry:Aviation
A colorless, odorless, tasteless, inert, gaseous chemical element. Krypton’s symbol is Kr, its atomic number is 36, and its atomic weight is 83.80. Krypton is used to fill fluorescent lamps.
Industry:Aviation
A colorless, odorless, tasteless, inert, gaseous chemical element. Nitrogen’s symbol is N, its atomic number is 7, and its atomic weight is 14.0067. Nitrogen makes up about 78% of the volume of the earth’s atmosphere and is used as an ingredient in fertilizers and explosives.
Industry:Aviation
A colorless, volatile, flammable liquid produced by the fermentation of certain types of grain, fruit, or wood pulp. Alcohol is used as a cleaning fluid, as a solvent in many of aircraft finishes, and as a fuel for certain types of specialized engines.
Ethyl alcohol (the alcohol used in liquor) is distilled from fruit or grain, and methyl alcohol, which is poisonous, is distilled from wood pulp.
Industry:Aviation
A colorless, volatile, flammable, aromatic hydrocarbon liquid which has the chemical formula C6H6. Benzene, sometimes called benzoil, is used as a solvent, as a cleaning fluid, and as a fuel for some special types of reciprocating engines.
Industry:Aviation
A column of rising air. Buildings and automobile traffic heat the air above cities and this heated air rises in a column, called a thermal.
Sailplanes gain altitude by circling in a thermal and being carried upward by it. Thermals are easily found, because clouds normally form at their top. Air containing water vapor is carried upward until it reaches a level at which the vapor condenses and becomes visible droplets of liquid water. These droplets form the cloud.
