Is cooking an egg an example of a physical or chemical change?
It would be like making kool-aid.You can separate the components of the mixture if you mix it up.
It's a chemical change.Is there a way to get the egg back to it's original form when you scramble it?Unless someone has managed time travel, there isn't.
A chemical.Your friend is wrong.Think about it.It has to be cooler than the freezing point to become solid.You cook an egg.
It is a mixture of both.At the same time, the egg's consistency changes.
