The boiling temperature of nitrogen is â195.8 Â°C (â320.4 Â°F), about 13 Â°C (â23 Â°F) below that of oxygen, which is therefore left behind. Nitrogen can also be produced on a large scale by burning carbon or hydrocarbons in air and separating the resulting carbon dioxide and water from the residual nitrogen.
