It is a chemical change as you are altering the chemical structure of the wood.
Burning wood is a chemical change. Although some might be confused on whether or not it is a chemical change it definitely is chemical change because when you burn wood, or mostly anything actually, a carbon dioxide gas is released into the air. As most might know a chemical change is when some type of substance reacts with another when in contact and it produces a new substance. In this case burning wood was created off of the burning chemicals in the wood, thus the carbon dioxide gas was released and exposed into the air.
its chemical change definitely chemical change
definite.
It can be both actually because if you start a fire your self and do it or if it is a wild fire. :)
its really physical.
Chemical--new compounds are created. Example: glucose becoming water and carbon dioxide.
Chemical change. Components in the wood combine with oxygen, releasing heat.
chemical change;because once you have burnt it you cant make it a piece of wood again.
Burning wood is a chemical change.
its a chemical change, because you can not reverse it
Chemical
The burning of wood is the oxidation of wood by combustion.
Oxidation is a chemical reaction where (usually) oxygen reacts with a chemical to form other chemicals and gives off heat (an exothermic reaction).
So the burning of wood is a chemical change. The resultant chemicals, (ash/soot/water/CO2...depending on the completeness of the reaction) are physically different to the wood, but the change is much more than physical.
No, it is a chemical change
Burning wood is a chemical change.
Burning wood is a chemical change because the reaction is not reversable and the end product is two separate chemicals.
Burning wood is a chemical change because you are altering the CHEMICAL structure of the wood.
it is chemical change
Combustion is a chemical process involving the oxidation. Burning wood is an example of this.
Chemical
A chemical change. The composition is being changed and mass is lost
Change of state from wood to ash can be described as physical change and burning of wood is through coming in contact with oxygen and hence it is both physical and chemical change.
it is a physical change
A chemical change. The substances present before burning are altered to something else by the end of the burning.

Is burning wood a physical or chemical property?
Neither. It is a chemical change. The ability of wood to burn is a chemical property.
Is wood turning into ash in a fire a physical change?
physical--no, it's chemical because a new substance is formed by burning logs/paper, and the new substance, ashes has a different chemical composition.
If you chop wood for a fire and then burn the wood you have made both physical and chemical changes.?
Yes, chopping is a physical change: the chemical composition of the molecules inside the wood remains the same. Burning causes the molecules in the wood to react with the air (mostly with the oxygen in the air), and the result is different compounds than before.
Is Burning wood is an example of physical change.?
I think you mean "Is burning a paper a physical change?" Burning a paper is not a physical change. It is a chemical change. Because you can't turn the ashes of the paper into a normal paper again. Examples of physical change: Cutting a paper, sharpening a pencil, writing on a paper... Examples of chemical change: Rotten egg, Rusted steel, molded bread...
What is the difference between a physical property and a chemical property of wood?
I'm not sure what the Chemical difference in property is, but the physical difference would be that ash is powdery and wood is solid.
Is burning of wood and paper a chemical or physical change?
Chemical change
Is the combustion of wood an example of a physical change?
Combustion (burning) is a chemical change.
Is burning wood a physical or chemical property?
Neither. It is a chemical change. The ability of wood to burn is a chemical property.
What physical change is shown taking place in burning wood?
chemical change.
Is a burning wood into ashes and smoke a physical or chemical change?
Burning wood is a chemical change - although, like most chemical changes it is accompanied by a physical change. Usually we reserve the term physical changes for things like erosion, melting, or evaporation where no change in composition occurs.
Is a tree being burned a chemical or physical change?
burning of tree or wood is an irreversible chemical change
What is an example of a chemical change wood burning glass breaking water freezing?
The chemical change is the burning wood because the products, carbon dioxide, water, ash, and soot, have different physical and chemical properties. The other changes are physical changes because the physical and chemical properties of the substances did not change.
Is wood turning into ash in a fire a physical change?
physical--no, it's chemical because a new substance is formed by burning logs/paper, and the new substance, ashes has a different chemical composition.

Is flammability a physical property of wood?
No, inflamabillity is a chemical property, because burning (of anything) is a chemical change.
