Sanding wood is a physical change because it does not alter the chemical composition of the wood. The process of sanding simply removes layers of wood through abrasion, changing its physical appearance and texture without changing its chemical structure. In contrast, a chemical change would involve a transformation at the molecular level, resulting in the formation of new substances with different chemical properties.

It would be a physical change because you are changing the shape of the wood not the chemical composition of the wood. However, you could possibly create a chemical change if you could hammer hard and long enough to burn the wood. Not likely, but it is possible.
The carving of wood is a physical change because the composition of the wood is not altered during the process. The wood is simply being reshaped into a different form without any chemical reactions taking place.
Caving wood is a physical change because the wood's chemical composition remains the same during the process. The shape and size of the wood may change, but the chemical structure of the wood molecules remains constant.
no, because the wood isn't changing itself, you are changing the wood.
Yes, it is a physical change.

It is a physical change, because you're giving the wood a new shape.
A physical change alters the form of the substance but does not change it into anything new. An example of a physical change is the boiling, freezing, melting, condensation of water. The result changes still give you water. A chemical change must make a new substance with new properties. An example of a chemical change is the burning of wood. The new substances made during complete combustion are ash, carbon dioxide, and water.
Cutting a piece of wood is a physical change because the chemical composition of the wood remains the same before and after cutting. The change is only in the physical appearance and shape of the wood.

A physical change because the chemical composition of the wood does not change.

Its a physical change
You're not changing the substance when you chop wood. Therefore, it is a physical change.
Wood is a material. It is not a change.
