The temperature of liquid nitrogen is −195.79 °C (77 K; −320 °F). This is the boiling point of nitrogen. However, nitrogen can exist as a liquid between 63 K and 77.2 K (-346°F and -320.44°F).

What temp does nitrogen liquify?

Liquid nitrogen (LN) is an inert cryogenic fluid with a temperature of − 196 °C [− 320 °F].

How does nitrogen liquify?

If air is cooled at atmospheric pressure, it remains a gas until the temperature reaches 81.6 K, 9 K below the liquification temperature of pure oxygen. ... Plunging an air-filled balloon into liquid nitrogen will lead to the liquification of almost all the air in the balloon.
