Good question? How do you tell that a hamburger undergoes chemical change when you cook the patty?
Explanation:
Chemical changes are characterized by the formation of new substances and the making and breaking of chemical bonds. In practice, this generally means a colour change or the precipitation of a new substance, or by the formation of a gas.
When you cook the patty, you certainly get the colour change, as the meat caramelizes and turns brown. You also get the aroma of the cooked meat - both processes indicate chemical change.
