Here's why:

* Non-condensable: Nitrogen remains a gas at normal atmospheric pressure and temperatures. It doesn't condense into a liquid or solid state unless subjected to extremely low temperatures and high pressures.

* Abundant: Nitrogen makes up about 78% of the Earth's atmosphere.

Other common examples of non-condensable gases include:

* Oxygen (O2)

* Argon (Ar)

* Helium (He)

These gases are often found in industrial processes and are important components in various applications.
