Chemical Change

Explanation:

apples turn brown because of a chemical reaction named oxidation which is cause by oxygen of the air

Oxygen is one of the most reactive chemicals known to exist ... There are a variety of oxidation reactions ... The fridge does not stop chemical reactions so bacteria will still rot the food eventually and out side of the fridge it would rot quicker than the fridge.
