when you separate the 2 main gases in the air, oxygen and nitrogen. this relies on them both having diff boiling points. nitrogen= -196 and oxygen= -187
first they have to compress and expand the air continuosly until it turns into liquid air. then you heat it, the nitrogen boils off first, and the oxygen is left at the bottom of the fractionating column. so then you have pure oxygen and nitrogen. they both now can be used for several things.
if your wondering what happens to the rest of thee siubstances oin the air well, carbon dioxide and the water freeze as water has got a freezing point of 0, and carbon dioxide has got a freezing pint of -78.
hope that helped :-)
all nobel gasses are obtained by fractional distillation of liquid air.
fractional distillation of air
Most of the gases in air, Nitrogen, Oxygen, Argon and others are obtained by fractional distillation of liquid air.
Liquefy it by cooling and reducing pressure and then do fractional distillation.
