Is a tree that is cut into boards at a sawmill a chemical change?

Sawing a board in half is not an example of chemical change. It is an example of a physical change. Physical changes on a substance do not change the substance. When you saw a board in half, the two halves of the boards are still boards- they're not anything else.

∙ 10y agoNo. It is not. A chemical change would involve the identity of the substance changing. The board is still made of wood after you cut it; therefore it is a physical change.
