chemical reaction.
It is a physical change because while the apple is cut into smaller pieces, it is still composed of the same materials. If you lit the apple on fire, that would result in a chemical change.
No it's a chemical change as you can't 'untoast' the bread.
It is a physical change because the apple is still an apple and nothing changed the composition of what's in the apple.
Eating an apple is both chemical and physical. By biting and chewing the apple you are causing a physical change in the apples general structure- nothing chemical. But when you swallow the apple and your stomach acid breaks down the apple and absorbs nutrients you are exerting a chemical change.

Cutting an apple is a physical change
This is a physical change. You only change the shape and size of an apple by slicing it. Chemical changes would mean changing the molecular composition of the apple.
Physical because it is still a apple just a part of it
It is a physical change because while the apple is cut into smaller pieces, it is still composed of the same materials. If you lit the apple on fire, that would result in a chemical change.
it is a chemical change
Physical change because you're just changing the shape of the apple, and not making the apple into a new substance
cooking an apple is causing a physical change because in a physical change, the IDENTITY of the substance never changes. (identity=atomic makeup. in a chemical change, the IDENTITY does change, due to a chemical reaction. because there is no change in the identity of the apple, baking it is a physical change
It is a chemical change - oxidisation.
No it's a chemical change as you can't 'untoast' the bread.
When you shape an apple differently than what it comes you have made a physical change. This is because you have not changed the chemical composition of the apple yet it appears differently.
An apple turning brown is a CHEMICAL change.
