it is a physical change because no reaction occurs and there is no new substance. :)
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.
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.
1. First step: a physical change 2. Second step: a chemical change
It is a physical change because the apple is still an apple and nothing changed the composition of what's in the apple.
it is a chemical change
Yes, it is a chemical property.
Cutting an apple is a physical change
Changing the color of an apple is a chemical change because it involves a chemical reaction that alters the molecular structure of the apple's pigments, such as when the apple oxidizes and turns brown.
chemical reaction.
Generally, white vinegar is often synthetic acetic acid, and cider vinegar is fermented from apple cider. The difference in cooking is one of flavor, as the two have similar chemical properties.
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
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
Fermenting is a chemical process.
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).
