It burn slowly or dies out.
If you remove fuel, oxygen, or both from a fire, the fire goes out.
Oxygen keeps the fire going. In some cases, it can make the fire larger, depending on the amount of oxygen around the fire.
That is, what they already do. No kind of fire can burn without oxygen!
There wouldn't be one. A fire needs oxygen in the first place.
It will go out. Fire needs oxygen, and a vacuum has none.
Fire goes out.
It would be of little to no consequence. The "burning" of the sun is not really fire; it does not use oxygen. The sun is instead powered by nuclear fusion, which turns hydrogen into helium.
it would go out, because for the fire to stay lit one necessity is oxygen.
The fire feeds off of the oxygen so the fire gets bigger. That's one reason you are told to keep doors closed when there is a fire.
The lack of oxygen for pure cunsumption of the fuel. If the fire has enough oxygen for the amount of whatever you are burning, no smoke.
It will burst into flames.
Limited only by the amount of oxygen available to it.
