Here's a bit more information:

* Boiling point: The temperature at which a substance transitions from a liquid to a gas.

* Freezing point: The temperature at which a substance transitions from a liquid to a solid.

* Nitrogen's freezing point: -210 °C (-346 °F)

So, at temperatures below -195.79 °C, nitrogen exists as a liquid. Between -195.79 °C and -210 °C, it exists as a liquid. At temperatures below -210 °C, it becomes a solid.
