Which of the following is not a physical change? a. burning wood b. cutting your hair c. ripping a shirt d. cutting down a tree

Well, a physical change would be a change where the item is still the item!

So if you'er burning wood, you're changing the wood chemically!

If you cut your hair, it's still your hair..that's physical.

Ripping your shirt, is still your shirt... physical.

and Cutting down a tree, it's still a tree! Physica.

So the correct answer would be A. Burning wood
