Nitrogen

Gaseous nitrogen is used in the chemical and petroleum industries for storage tank blanketing and vessel inerting applications. It is also used extensively by the electronics and metals industries for its inert properties. Liquid nitrogen, produced by the cryogenic air separation process, finds wide use as a refrigerant in applications such as cryogenic grinding of plastics and food freezing. 

 Nitrogen (N2) constitutes 78.03% of the air, has a gaseous specific gravity of 0.967, and has a boiling point of -320.5
