Nitrogen constitutes 78% of the atmosphere and is a constituent of all living tissues. Under normal conditions, nitrogen is a colorless, odorless and tasteless inert gas which has no toxic properties and is slightly lighter than air. As a liquid at -320 °F it has a water-white appearance and must be handled with care due to its low temperature.
