1. First step: a physical change
2. Second step: a chemical change
Digesting an apple is a chemical change because the enzymes in your digestive system break down the complex carbohydrates, proteins, and fats in the apple into simpler molecules that can be absorbed by the body. This process involves the chemical breakdown of the apple's nutrients.
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.
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 physical change because the apple is still an apple and nothing changed the composition of what's in the apple.
it is a physical change because no reaction occurs and there is no new substance. :)

Yes it is.
it is a chemical change

Cutting an apple is a physical change
The digestion of food through the alimentary canal involve a series of chemical and physical changes. In the example of pizza its bread component undergoes chemical changes as it is digested by amylase enzymes in saliva. Other chemical changes include hydrochloric acid of the stomach "attacking" and digesting proteins found in the pizza.
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.
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.
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
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.
Physical change because you're just changing the shape of the apple, and not making the apple into a new substance
