Why is the boiling point of liquid nitrogen low?
Answers
Answer:
The weak van der Waals interaction between the N2 molecules results in little interatomic interaction, manifested in its very low boiling point. The temperature of liquid nitrogen can readily be reduced to its freezing point −210 °C (−346 °F; 63 K) by placing it in a vacuum chamber pumped by a vacuum pump
Answer:
Why is the boiling point of nitrogen very low?
Nitrogen is a significantly lighter atom and it exists as N2 predominantly. Because of this diatomic nature and high stability that arises due to it,it prefers to exist in the existing state instead of interacting with other nitrogen atoms. Since N2 is very stable and inert,it doesn't interact well with other N2 atoms as well. We must remember that boiling point is a physical property and it arises dude to intermolecular interactions. There are weak van der walls forces of attractions between the molecules. The energy required to overcome these forces is very low since the force depends only on mass. Therefore, due to the low mass and inertness of N2 , the forces are poor and very minimal thermal energy is required to overcome the forces. ie: around -190 celcius Temperature is enough to impart kinetic energy to the molecules to overcome van der walls forces. That is the reason.
