Combustion
This is the burning of a substance in the presence of oxygen.
Combustion or burning is the chemical reaction of a substance in the presence of oxygen. This can be understood with a simple example. Fire is not enough to burn a paper, it also require oxygen in air. During burning or combustion, heat energy is generated and physical and chemical properties of substance are changed.
Some evidence that a chemical change is occurring when magnesium is burning in the presence of oxygen include the formation of a white powdery substance (magnesium oxide), the emission of light and heat, and the change in physical properties of the magnesium (e.g., color change or formation of ash).
Burning is an oxidation reaction - a reaction with oxygen.
The ability of a substance to react in the presence of oxygen and burn when exposed to flame is known as flammability. It is a measure of how easily a material can ignite and sustain combustion in the presence of oxygen. Materials with high flammability are more likely to catch fire and burn rapidly.
Combustion
Oxygen
Burning is a chemical process - oxidation - that usually takes place where oxygen from the air reacts with the substance that is burning. The surface area determines how much oxygen is in contact with the substance.
combustion
The burning substance of a substance refers to the part of the substance that undergoes combustion or oxidation when exposed to heat or a flame. This process typically involves the release of heat, light, and often the production of new chemical compounds as the substance reacts with oxygen in the air.
