What is the difference between burning steel wool in air and burning it in a pure oxygen?
burns faster in pure oxygen as the percentage of oxygen is less in air
Does pure oxygen make things burn faster?
In general, no, it accelerates / increases fires. If the fire is based on methane, say, and the oxygen displaces all the methane, then the fire will go out. If the oxygen is passed through / across the fire at something approaching supersonic speed, if the fire doesn't go out, it *will* go somewhere else.
Is pure oxygen explosive?
No. Oxygen itself is not flammable, but it is necessary for fire. Fire is a chemical reaction between oxygen and a flammable substance. Fire is possible on Earth because ordinary air is 21% oxygen. Pure oxygen is considered a fire hazard because higher concentrations of oxygen will make it easier for a fire to ignite and will allow it to burn hotter and faster than normal.
Why do iron and magnisium burn more in oxygen than in air?
Iron and magnesium burn in air under the right circumstances becasue they combine rapidly with oxygen. (Fire is just the rapid combination of oxygen or another oxidizer, wiht a fuel.) Oxygen is only about 20% of air. If you provide pure, 100%, oxygen under the same circumstances, there is more oxygen to combine with the iron or magnesium, so they can burn faster.
Why pure NH3 does not burn in air but impure PH3 burn in air?
With traces of P2H4 present, PH3 is spontaneously flammable in air
What substances burn faster in oxygen?
Any substance that burns in air is likely to burn faster in pure oxygen, if all other conditions are equal.

Does pure hydrogen burn in the absence of air?
No hydrogen will not burn in the absence of air unless another oxidizer is present.
If you put a match in pure oxygen will the oxygen burn?
No, oxygen itself does not burn. Oxygen only supports and accelerates combustion when there is a fuel source present. So, while the match may burn more intensely in pure oxygen, the oxygen itself does not burn.

Why does sulfur burn more rapidly in oxygen than in air?
Well, oxygen supports burning. Fire needs fuel, oxygen and a spark or another source of ignition. So the more oxygen there is, the faster your substance will burn! There is 21% oxygen in air, and when you have an atmosphere of oxygen, it can go to quite high concentrations. So sulphur will burn in an atmosphere which has a higher oxygen content.
Will pure oxygen burn your lungs?
It can damage your lungs and eyes.
Why do iron and magnisium burn more in oxygen than in air?
Iron and magnesium burn in air under the right circumstances becasue they combine rapidly with oxygen. (Fire is just the rapid combination of oxygen or another oxidizer, wiht a fuel.) Oxygen is only about 20% of air. If you provide pure, 100%, oxygen under the same circumstances, there is more oxygen to combine with the iron or magnesium, so they can burn faster.
How to make a fire burn at 1980 degrees Fahrenheit?
You blow pure oxygen on it or supply it with pure oxygen. It gets white hot to the point that it will blind you.
Can oxygen be dangerous?
Yes. Oxygen is needed for flammable objects to burn. In increased concentrations oxygen will cause flammable materials to burn faster, and more intensely and allows them to ignite at lower temperatures.
Why do you burn food in oxygen and not in air?
Burning food in pure oxygen (rather than air) accelerates the combustion process because oxygen is the key component needed for fire. Air is a blend of gases, with only about 21% oxygen, while pure oxygen provides a more efficient environment for combustion to occur. This allows for faster and more intense burning of the food.
