Physical... Chemically it's still cheese - but the shredding changes its appearance.
It is changing from a solid to a liquid, which is a physical change.
Fermenting cheese is considered a chemical change because it involves the breakdown of proteins and fats by the action of bacteria, enzymes, or other microorganisms, leading to the formation of new compounds and flavors. This results in the transformation of the cheese at a molecular level, which is why it is classified as a chemical change rather than a physical change.
OK I am actually learning this in my science class right now. So here's what i learned. I think you are thinking of shredded cheese in the wrong way. It is not actually the shredded cheese, but the act of shredding cheese. A physical property or a physical change, is something that happens to an object, but does not change what the object, itself, is. So if you shred the cheese, sure you are breaking the cheese up into tiny pieces, but it is still cheese.But the making of cheese, is a chemical change. because you actually took different objects and changed them so that they were no longer the same object, but a completely new substance.
Grating cheese is a physical change because it alters the size and shape of the cheese without changing its chemical composition. When cheese is grated, it is simply cut into smaller pieces, which allows it to melt more easily or be incorporated into dishes. The fundamental properties of the cheese, including its taste, smell, and nutritional content, remain unchanged throughout this process.
A physical change that takes place when making pizza is when the cheese melts because a new substance is not created. Another physical change is the pizza increasing in size while it cooks.

No. Fermenting is a chemical change.
It's Chemical, Because if you combine cheese from milk it will Change it appearance.

The question to answer is "Has a new substance been created?" Most cdertainly heating does change the cheese, milk and eggs used in most mac and cheese recipes. So the answer is, yes, cooking mac and cheese is a chemical change.
As long as you don't burn the cheese while heating it, the change is purely physical.
Yes. Remember that a chemical change produces a new substance.

Cheese molding is a chemical change because the microorganisms present in the environment break down the proteins and fats in the cheese, leading to the formation of new compounds. This process cannot be reversed, unlike physical changes where the structure or state of a substance can be changed without altering its chemical composition.
"A physical change is any change not involving a change in the substance's chemical identity. Matter undergoes chemical change when the composition of the substances changes: one or more substances combine or break up (as in a relationship) to form new substances" From This I gather that its a physical change as the cheese isn't changed into another substance, The cheese doesnt change, for example it doesnt taste or smell different, But its physical propertys do change it looks different
Fermenting cheese and grating cheese are chemical changes.
I assume you mean chemical "change" and the answer is no, it is a physical change that takes place.
