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.

∙ 9y agoCombustion, or burning, is a chemical change because the resulting product has a different chemical composition that the beginning substance. A physical change would be when the appearance of the object changes, but the chemical composition remains the same.

Is fireworks a physical change?
No. Fireworks are an example of a chemical change called combustion.
Is forest fire a chemical change?
Yes, because any time something is burning, or is burnt there is a chemical change.
Is combustion a physical change or a chemical change?
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.
Does a chemical change occur when a piece of wood is painted?
When you burn wood a chemical change occurs.
Wood roating is a physical or chemical change?
when wood rots it is a physical change and not a chemical change.
Is the combustion of wood an example of a physical change?
Combustion (burning) is a chemical change.
Is heating a wood splinter a chemical change and why?
Heating the wood (and not burning it) would be a physical change. If the wood splinter catches fire and burns, then it is a chemical change because a combustion reaction has taken place and the wood is no longer the same chemical composition. It will turn into carbon dioxide and water, and other materials left over.
Is fireworks a physical change?
No. Fireworks are an example of a chemical change called combustion.
Is forest fire a chemical change?
Yes, because any time something is burning, or is burnt there is a chemical change.
Is wood burning a chemical reaction or a physical reaction?
The burning of a wooden stick is a chemical process.

Burning wood a physical or chemical?
Burning wood is a chemical reaction because combustion (burning) is an oxidation reaction.
Is burning wood into charcoal a physical change?
Unfortunately, it is not a physical/reversible change, as combustion causes chemicals to change their bonding. A simpler example than wood would be glucose (the same reaction as in respiration): C6H12O6 + 6O2 --> 6CO2 + 6H2O This reaction is not reversible.
Is combustion a chemcial change?
Combustion clearly is a chemical change. In the combustion of a hydrocarbon, for example, you begin with the hydrocarbon and after combustion you end up with carbon dioxide (CO2) and water (H2O). This demonstrates that a chemical change has taken place.
Does a chemical change occur when a piece of wood is painted?
When you burn wood a chemical change occurs.
Is combustion of gasoline a physical change?
Combustion of gasoline changes the chemical properties of the matter, and is thus a chemical change, not a physical one.
Example of physical and chemical?
A physical change is melting.A chemical change is combustion.
