Nitrogen (N2)

Nitrogen (N2) is a diatomic gas, meaning it's normal state or molecule is made up of two atoms, which comprises 78 percent of the earth's atmosphere. Colorless, odorless, tasteless, and nontoxic, nitrogen exists as a non-flammable gas at atmospheric temperatures and pressures.

A specific gravity of .9669 makes nitrogen slightly lighter than air. When cooled to its boiling point of -320°F, nitrogen becomes a colorless liquid which can, in turn, be compressed into a colorless, crystalline solid. It is only slightly soluble in water and most other liquids, and is a poor conductor of heat and electricity. While not a true inert gas Nitrogen does display many of the traits of an inert gas at standard temperatures and pressures.

Common uses of Nitrogen?

Nitrogen is used primarily for its inert characteristics in blanketing and pressurization such as packaging fresh foods and pressurization beer. It is also used in a liquid form for cryogenic cooling for testing and shrink fitting applications.
