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.
Cows milk, not cheese, goes into making cheddar
Chocolate milk is a physical change because the ingredients (milk and chocolate) are mixed together but their chemical composition remains the same. No new substances are formed during the process of making chocolate milk.
cheese
Physical change, because you are not permanently changing the substance. Also you can change the two substances back to how they originally were
Yes, it is a chemical process.
Cheese is made from milk, and cheese can be preserved more easily than the milk from which it is made.
"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
Chocolate milk is a mixture. It is not a change of any sort. The making of chocolate milk is a physical change as none of the components change their chemical identity.
Making skim milk involves the physical separation of cream from whole milk, rather than using chemical properties. This process typically utilizes centrifugation or gravity to separate the fat content from the liquid. While the fat and water in milk have different physical properties, such as density, the process does not alter the chemical composition of the milk itself. Therefore, it is more accurate to describe this as a physical separation method rather than a chemical one.
Physical.
It is not physical but rather chemical: milk sugar (lactose) is converted to lactic acid by Lactobacillus bacteria.
