It will depend on atmospheric pressure. You can use the Clausius-Clapeyron equation In this form

ln (P2/P1) =( or approximately equals )= -ΔHm ( 1/T2 - 1/T1 )/R

The normal bp of N2 is 77.4 K at 760 Torr, ΔHm for N2 is 5.58 kJ/mol, R is 8.314 J/mol.K. Plug in above constants, and you can supply your own temp or pressure into T1 or P1 and solve for the other. Make sure you get your units right! I leave it up to you to work them out.

This only works for ideal gases close to the normal boiling point.

Why N2 has lower boiling point then CO?

NO2 has a higher boiling point than CO2 because the nitrogen radii is larger than carbon. The bigger the atom the more intermolecular force that is created...this requires more energy to break causing a higher boiling point.


Nitrogen is a gas?

Which of the following should have the lowest boiling point nh3 n2 hf H2O or na2s?

Among the options provided, nitrogen gas (N2) should have the lowest boiling point. Nitrogen is a diatomic molecule with weak van der Waals forces between its molecules, leading to a relatively low boiling point compared to ammonia (NH3), hydrogen fluoride (HF), water (H2O), and sodium sulfide (Na2S) which have stronger intermolecular forces due to hydrogen bonding or ionic interactions.
