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.
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.

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.
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.
It is a physical change, because you're giving the wood a new shape.
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.
Physical-it is still wood, just in small pieces
A physical change because the chemical composition of the wood does not change.

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

Do the logs change from wood to some other substance? No, so it has to be a physical change.
