1.Nitrogen is usually called an inert gas. It is used in some inert atmospheres for metal processing and in bulbs to prevent arcing, but it is not chemically inert. 2.It is an essential element in the life of animals and plants, and is a component of many useful compounds. Nitrogen combines with many metals to form hard nitrides, which can be used as wear-resistant metals. A small amount of nitrogen in steel will inhibit grain growth at high temperatures and will also increase the strength of certain steels. It can also be used to produce hard surfaces on steel. 3.Liquid nitrogen is used during food freezing.
