Oxygen is liquified by a process called fractional distillation. even though the exact methods differ this is a basic description. Atmospheric air is usually super cooled ( but it doesn't have to be). From there it is seperated into the different gases that make up air i.e. oxygen, nitrogen, etc. Each gas has a different boiling point (oxygen is something like -300 F) and as a gas is boiled off it is collected and condensed under very cold temperatures. The condensed gas is usually kept under a low vacuum so as to lessen the temperature it must be kept.

The temperature has to be really cold in order to liquify oxygen.

U can Liquify oxgen by two methods theroticaly...'coz
Volume = Constant/ Pressure
Volume= constant/ Temperature

To convert gaseous oxygen into liquid oxygen, u need to either increase the pressure inorder to decrease the vol. ( which will convert it in to liquid), or increase the tempreature to decrease the volume of oxygen

Oxygen properties
Melting Point : -214 degC changes from a solid to a liquid
Boiling Point : -183 degC changes from a liquid to a gas
at ambient pressure.

The temperature values change with pressure. The higher the pressure the lower the temperature needs to be to achieve a change of state. The state of a material is a function of pressure and temperture.

Get it cold- REALLY cold. I found a website demonstrating a simple technique that involves liquid nitrogen.
http://www.kyantec.com/Tips/LiquifyingOxygen.htm

A balloon full of oxygen is slipped over a test tube. The test tube is then lowered into liquid nitrogen which chills the gas enough to condense it into liquid. Once it gets above -196 degC (at one atm of pressure), it will vaporize again.
I'm not sure how they do this on a larger scale, but it seems like a cool expirament.

pressure the physical mass of oxygen becomes cold and liquid when constrained to a fraction of it's original area within a container can also be liquid when two hydrogen molecules are added

bring the temperature down

By cooling it and pressurizing it.

Cool it to -218.79C/-361.82F/54.36K

Or put it under pressure
