in a way, oxygen is one of the raw material in a way to start a fire. Without oxygen, it is not possible to start a fire.
oxidation
burns faster in pure oxygen as the percentage of oxygen is less in air
Burning, or combustion, in a scientific context refers to a chemical reaction between a fuel and oxygen that produces heat, light, and often other byproducts such as carbon dioxide and water vapor. This process is exothermic, meaning it releases energy in the form of heat.
Burning is an oxidation reaction - a reaction with oxygen.
Combustion is the scientific term for the process of burning. During combustion, a substance combines rapidly with oxygen to produce heat and light.
Combustion (or burning) is the reaction between a fuel and any oxidant. So by definition burning requires oxygem, As to why oxygen supports burning because it is very reactive and when any when any chemical is oxidiesed it is an exothermic reaction
The product of hydrogen burning in oxygen is water (H2O). The chemical reaction between hydrogen and oxygen produces water molecules along with heat energy.
Oxygen is the oxydant in the reaction of burning.
Oxygen is a necessary ingredient for burning.
to stop oxygen for burning
It is possible to break bonds between oxygen by supplying heat and this process takes place in all burning / oxidation reactions.
If there is no oxygen, a burning candle will not be able to sustain the combustion process since oxygen is needed for the flame to continue burning. The candle will eventually go out in the absence of oxygen.
