Liquid Nitrogen
Colourless, tasteless, odourless, and nontoxic, nitrogen is
virtually inert under most conditions. It makes up 78% of the air on earth. Air separation
plants extract nitrogen from liquid air in large quantities. The gas turns into a liquid at
-195.2°C (-320.4°F).
Uses
In liquid form, nitrogen is used for quick freezing, preserving food for transport,
storing biological materials, cryosurgery, and grinding plastics and rubber.
Nitrogen gas mixtures are also commonly used in fire extinguishers and fertilisers.
