Nitrogen is inert, odorless, colorless, non-inflammable, and non-corrosive. Commercially, liquid nitrogen is made by compressing and condensing nitrogen gas to a temperature below its evaporation point, which is roughly 196°C. Cryogenic refrigeration is the most typical application of liquid nitrogen.

Uses. Nitrogen is important to the chemical industry. It is used to make fertilisers, nitric acid, nylon, dyes and explosives. To make these products, nitrogen must first be reacted with hydrogen to produce ammonia. This is done by the Haber process. 150 million tonnes of ammonia are produced in this way every year.
