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...

Burning wood in the fireplace is an example of a chemical change because the wood undergoes a chemical reaction to produce heat, light, and ash. This change is irreversible as the wood is transformed into new substances during the process.
Chopping wood for a fire is a physical change because the wood's size and shape are altered. Burning the wood is a chemical change because it undergoes a chemical reaction to produce heat, light, and other byproducts.
a chemical change involves the formation of a new compound, whereas a physical change just changes from one form/state to another. An example is boiling water changes it from a liquid to a gas but it's still water(H2O) so thats a physical change. However somthing like metal rusting involves the addition of oxygen so iron rusting would go from Fe to FeO2 which is a new substance, hence a chemical change. Carving wood (though not an element as in this example) causes a physical change but not a chemical change.
The match burning and leaving a charred stick of wood is a chemical change. This is because the chemical composition of the wood is altered during the burning process, causing a new substance (char) to be formed.
Combustion (burning) is a chemical change.
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.
chemical 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.

No, it is a physical change. If you think about cutting the wood, the pieces will be smaller than the log, but they will have all of the same properties as they did when they were put together. An example of a chemical change is burning the wood. The act of burning it would be a chemical change since it is converting the wood into carbon and water vapor.

Burning wood. When the wood is burned, it becomes black.
physical change
A physical change is a change that can be undone. A chemical change cannot be undone. An example of this would be dissolving salt in water. This is a physical change because if you let the water in the container evaporate the salt will be left behind. A chemical change would be like burning a piece of wood since you cannot undo the change taking place to the wood.
