how is oxygen combustible but not flammable? If it feeds the fire isn’t it essentially the same thing?
In: Chemistry
Oxygen is neither of those things. Let’s start with the definition of “combustion”
> Combustion: rapid chemical combination of a substance with oxygen, involving the production of heat and light.
Oxygen is not capable of combustion, thus not combustible. (Yes, there are exotic oxygen + oxygen reactions, but they produce no heat.)
Similarly:
> Flammable: a substance is one that burns.
Nope, you can’t burn oxygen either.
