Nitrogen is a pure, elemental substance. Any such substance has constant physical properties such as melting point, and boiling point.

Explanation:

Nitrogen is characterized by a boiling point of -196^"o" C. At this temperature its vapour pressure is 1 atm. Why is the boiling point of nitrogen so low? Well, only weak dispersion forces operate between the nitrogen molecules.
