Combustion is a chemical reaction. It is most commonly a reaction with oxygen gas (O2), in which the material combusting combines with oxygen.
It is a phiscal change because the combustion doesn't change. I'm in the 7th grade and nobody older than me answered this question! That is a shame!

No. Fireworks are an example of a chemical change called combustion.

Combustion is basically a chemical reacting with oxygen to become the oxide and water is produced. So when alcohol combusts, for example, it is changed (burned) to carbon dioxide and water. In other words, there is a chemical change.
Burning anything (a liquid or a solid) is a chemical change and the reaction is known as a combustion reaction.
The combustion of wood is a chemical change because the products water, carbon dioxide, soot, and ash, all have physical and chemical properties that are different from the reactants wood and oxygen.
Combustion (burning) is a chemical change.
A physical change is melting.A chemical change is combustion.
Combustion of gasoline changes the chemical properties of the matter, and is thus a chemical change, not a physical one.

the physical comes from the chemical explosion
NO its a chemical change for it can't be reversed
It is a chemical change; burning (combustion) is a chemical process.
No combustibility- it is a property. However, COMBUSTION is a chemical change.
Combustion is a chemical change, so the burning of a tree will be a chemical change.

Chemical, an explosion is essentially extremely fast combustion which is a chemical reaction.
