Difference Between Liquid Nitrogen and Nitrogen Gas

Dec 18, 2017What is Nitrogen Gas. Nitrogen gas (N 2) is a colorless, odorless gas which makes up roughly 78% of the earth's atmosphere.It is an inert gas. The molar mass of nitrogen gas is 28.014 g/mol. Nitrogen gas is slightly lighter than normal air.. Nitrogen gas can be converted into liquid nitrogen at temperatures below the boiling point of nitrogen. Nitrogen can solidify at temperatures Get price
