Liquid nitrogen
Liquid nitrogen is inert, colorless, odorless, non-corrosive,
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.
