Want this question answered?
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.
It is primarily chemical change which has physical consequences.
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.
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.
Fermenting cheese and grating cheese are chemical changes.
fermenting

It needs to be a hard cheese like, Parmesan Cheese or Romano Cheese.
No. The cheese is still cheese, it's just in pieces now.
No but because you usually can't grate every bit of a block of cheese (for fear of grating your fingers!!) you are usually left with a little chunk at the end.

No. Fermenting is a chemical change.
it is a chemical change.
As long as you don't burn the cheese while heating it, the change is purely physical.
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.
