Is it true that you can use pure oxygen gas to make combustion?

Question

And if it is,how does it work

Answer 1

Pure (& even not so pure) oxygen will ignite/explode when exposed to a flame.  In fact, it's the amount of oxygen in the atmosphere that allows fire to exist on Earth at all.

Answer 2

Put something that will burn in pure oxygen(clothes, oil, wood etc), light it and you have a combustion reaction.

Now if you were asking if pure oxygen will combust by itself then the answer is no. Oxygen does not burn(combust) by itself but it is needed for a combustion reaction to occur.  

Answer 3

You're kidding right???

OF COURSE that's how it works.  Oxygen is required for almost all forms of combustion.  and it doesn'tt have to be "pure" -- just light a match and watch it work.

But if you use PURE oxygen, you can do some amazing things.  Mix oxygen and acetylene gas, and you can make a fire that will burn through steel!  Put that same steel in a pure oxygen enviroment, and it will catch fire like a piece of paper.  Light a fire in a pure oxygen atmosphere and it will explode like a bomb.  That's kinda what happened on Apollo 1 in the 1960's. And that's why you can't smoke in hospital rooms.
