Liquid nitrogen is inert, colorless, odorless, noncorrosive, nonflammable, and extremely cold.
Nitrogen makes up the major portion of the atmosphere (78.03% by volume, 75.5% by weight).
Nitrogen is inert and will not support combustion; however, it is not life supporting.
Nitrogen is inert except when heated to very high temperatures, where it combines with some of
the more active metals, such as lithium and magnesium, to form nitrides. It will also combine with
oxygen to form oxides of nitrogen and, when combined with hydrogen in the presence of catalysts,
will form ammonia.
Although used more commonly in the gaseous state, nitrogen is commonly stored and transported
as a liquid, affording a more cost-effective way of providing product supply
