Chemistry & Biology : How to Make Oxygen a Liquid

In order to make liquid oxygen, oxygen needs to be changed from its gaseous form into a liquid, and this occurs at -183 degrees Fahrenheit. Use several cycles of cooling and compression to turn oxygen into a liquid with help from a science teacher and field biologist in this free video on chemistry.

so why you don't show us how to make it?

I like those blue sperms on your wall

"-183 degrees Fahrenheit"

Your description is wrong. It is -183 degree C

Yes and no... I do understand what you're saying, you cant have a chemical reaction without both reactants. So yes you are correct, oxygen is a combustion enabler.

However in a closed environment combustion will become more violent, even explosive with the addition of more oxygen. Things that wouldn't burn under natural conditions (like steel) will easily burn in a 100% oxygen atmosphere. Oxygen is a combustion enhancer (hazardous oxidizer) so it falls into a different category.

@AlphaMark3 well isnt combustion just when something reacts with oxygen?

[ATHYROSTOMOS95]

well you are very good at explaining but it could be mucheasier if we had a video guide.the real experiment.good job

[AlphaMark3]

not flammable...it is a "Hazardous Oxidizer" it makes everything else REALLLLLYYYYY flammable.

[wolfcrapshit]

Sooo how can i make it! put videos, pictures i am boring of you talking, i need proff! videos!!! pictures

[xawohani6]

what is your problem people listen and learn

[sargeantneo1]

what?

if you let the mixture heat up the oxygen will boil before the nitrogen cause it has a lower boiling temprature.
