A carpenter sands a wooden board until it is smooth. Is this a physical or a chemical change?

Answers

Answer 1

Answer:

When a carpenter sands a wooden board until it is smooth this is a physical change, because the chemical properties of the wood are not changed, only its appearance. It is still wood just a bit more smooth. This means that this change doesn't change what the substance (the wood) is. A chemical change on the other hand is change in which a new substance is formed and energy is either given off or absorbed.

Answer 2

Answer:
This is a physical change. Because he is not changing what it is just its outward appearance. hope this helped.
