the reason that decomposition of an apple is chemical change is that the decomposition is actually the apple being eaten by microorganisms such as bacteria, and inside of themselves they are performing chemical changes on the glucose and other sugars they get from the apple.
Decomposition is the process of a compound breaking up into the elements it was comprised of. For example, in electrolysis water decomposes to create hydrogen and oxygen. Because the chemical bonds holding the hydrogen and oxygen molecules were broken, decomposition is a chemical change.
The thermal decomposition of baking powder is 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.
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.

Thermal decomposition is a chemical change.
it is a chemical 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.
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
An apple decays over the period of around 1-2 months depending on the conditions that it is in. To help with the decomposition process, humidity in the air can attract insects to decay the apple.
The thermal decomposition of baking powder is a chemical change.
An apple turning brown is both a chemical and a physical change. Physically it changes appearance by turning brown. Chemically it oxidizes when the air comes in contact with the enzymes and chemicals in the fruit.
Cutting an apple is a physical change
The thermal decomposition of baking powder is a chemical 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.
Melting is a physical change; but above a temperature the thermal decomposition of butter begin - this is a chemical change.
