I think so it is most likely to be Chemical Change. I am actually a hundred percent sure that it is chemical change. I will also be answering this question on Yahoo Answers. Just search up this question and when you see a picture of Victoria Justice and Ariana Grande then that is me. You can then see all my questions that I have answered about science.

Answer 4

Frying a hamburger represents a chemical change. The reason for this is that the heat alters the chemical nature of the meat, turning some of it into charred or denatured protein, etc. It it is heated to a high enough temperature, some of the ingredients in the meat may even turn into carbon dioxide and water, a combustion reaction of organic molecules.

Answer 5

When you cook something, two main things are going on. First, the water is being evaporated out. Second, proteins are being denatured. So yes, cooking is a chemical change.

Answer 6

chemical change, because after the meat is cooked you can never return the meat back to red... the change is irreversible, thus it is a chemical change.

Answer 7

It is a chemical change. Heat activates a chemical reaction between the protein and oxygen. The oxygen in the air reacts with the proteins and the chemical bonds are broken.
