Answer
Brief Explanations:
- Baking a cake involves chemical reactions like the breakdown and combination of ingredients at high - temperature, so it's a chemical change.
- Smashing a soda can only changes its shape, not its chemical composition, so it's a physical change.
- Shredding paper only changes the physical form of the paper, not its chemical nature, so it's a physical change.
- Chopping wood only changes the physical size and shape of the wood, not its chemical makeup, so it's a physical change.
- Burning wood involves a chemical reaction with oxygen, producing new substances like carbon dioxide and ash, so it's a chemical change.
