no it depends on the pressure of it.

No, when totally liquified and then put through a Fractional Distillation process, each of the components have a different Boiling Temperature. The 2 main components of the air are as follows: -
When in liquid form at atmospheric pressure, Oxygen boils at
-183°C, and Nitrogen at -195°C.
(The higher boiling fractions in the air are first removed by other processes. If not, they would solidify at the cryogenic temperatures and block up the processing equipment).
(Sillyturtledad, a pure liquid (like pure water for example or Butane ... etc...have fixed Boiling Points.
At atmospheric pressure at sea level, Water = 100°C,
Butane = -0.5°C and Propane = -42°C ....etc..etc.)

No because it is a mixture not a pure substance each gas in air has a different boiling point. Air is seperated by fractional distillation and the gases are used for differnet industrial processes nitrogen to make ammonia and for use in refrigerated lorries, and filling crisp packets, oxygen for use in the basic oxygen steel making process as well as the production of sulphuric acid, need I go on?

Nothing has a fixed boiling point. Changing the pressure will change the boiling point.
Typically lowering the pressure lowers the boiling point and vice versa. As a result, water boils at a lower temperature in denver, colorado than it does in death valley.
Norrie,
Sure, at a certain pressure, they have a fixed boiling/melting point, but by changing the pressure, you change the boiling point. By definition, then, it does not have a fixed boiling point.

Air is a mixture of gasses so each constituent will have its own boiling point. I think carbon dioxide is the first to liquify when air is chilled, followed by nitrogen.

I think the boiling point is near -270 deg Celsius.
Rather cold.

Air does not becuase air can be a mixture of elements. these elements can vary becuase of polutants in the air. Pure Oxygen will.
