DEF

A chemical compound which appears under the form of a noncombustible, asphyxiating, colourless, sweet-tasting gas, is soluble in alcohol, ether, and concentrated sulfuric acid, is slightly soluble in water, is derived by thermal decomposition of ammonium nitrate, controlled reduction of nitriles or nitrates, supports combustion, can form explosive mixture with air, narcotic in high concentration, and is used as an anesthetic in dentistry and surgery, a propellant gas in food aerosols, and for leak detection.

OBS

Nitrous oxide is destroyed by ultraviolet light and has a 150-year residence time in the atmosphere. Concentrations of nitrous oxide are increasing presently at about 0.3%, or 0.7 ppb [part per billion], per year. A 50% increase of the present concentration would raise the mean global temperature between 0.2 and 0.5 C.

OBS
