Questions and Answers - How cold is liquid nitrogen?

How cold is liquid nitrogen? Under normal atmospheric pressure, nitrogen can exist as a liquid between the temperatures of 63 K and 77.2 K (-346°F and -320.44°F). Below 63 K, nitrogen freezes and becomes a solid. Above 77.2 K, nitrogen boils and becomes a gas.How can you separate nitrogen from liquid air?,By cooling and pressing air and then expanding it you can separate liquid nitrogen from air.,At 77 K, the liquid nitrogen boils off as a gas and is collected.
