* Bose-Einstein condensates require extremely low temperatures: BECs form when a gas of bosons is cooled to near absolute zero (-273.15 °C or -459.67 °F). Liquid nitrogen, while a cryogenic fluid, has a boiling point of -195.79 °C (-320.22 °F). This is significantly higher than the temperatures needed for BEC formation.
* Liquid nitrogen is a liquid, not a gas: BECs are formed from a gas of bosons, not a liquid. While nitrogen exists in a gaseous state, it is in a liquid state when it is referred to as "liquid nitrogen."
* Liquid nitrogen is not composed of bosons: Nitrogen atoms have a nuclear spin of 1, which makes them fermions. BECs require bosons, which are particles with integer spin.
In summary: Liquid nitrogen is a cryogenic fluid, but it does not meet the requirements for forming a Bose-Einstein condensate.
