Hi. It's not. Air has a mixture of gasses which each become liquid at different temperatures at a given pressure.

Compressing air causes the temperature to rise. PV=nRT

If you take for example Oxygen (same in Nitrogen and so on)
as gas the Molecules (O2) have sooo much space around each ohter and moving realy fast (couse of ther energy)
if you cooling them down, they have to exhaust their energy due to the law (p*v=n*R*t=Energy) to hold Volume and pressure. by this way they are slowing down and coming more near, forming a liquid.
You can achieve the same if you change the pressure (by compressing it) or by decrease the volume or increase the number of molecules

because of the pressure
