An apple turning brown is a CHEMICAL change.
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
When an apple rots, it's more of a chemical change. Sure, you can SEE the change in it..but the look, is not the actual change. It is a chemical change, catalysed by an organism. The apple wouldn't rot, if there were no chemical change.
No, cutting an apple in half is not a chemical change. Cutting an apple is doing nothing but changing the shape and form of the apple, but in the end, it's still an apple.
If you cut an apple and keep, the colour changes to brown. This is physical change. Apple has iron (in the form of ferrous salts). The colour is due to the formation of harmful ferric compounds and this is a chemical change (conversion of ferrous to ferric).
Cutting an apple is a physical change
An apple turning brown is a CHEMICAL 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.

1. First step: a physical change 2. Second step: a chemical change
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.
Physical change because you're just changing the shape of the apple, and not making the apple into a new substance
Fermenting is a chemical process.
It's physical! If you change the size, it's still an apple!
