Is melting butter a physical change or chemical change?
As you may know, determining whether a change is chemical or physical can sometimes be a real pain! This particular change is a hard one. If your talking about butter slightly melting on a hot day because it was left out on the counter, THAT is a physical change and is reversible by simply putting the butter into the fridge. However, melting butter on the stove and having it completely turn to liquid and turn a little brown, THAT is a chemical change and is hard to reverse... a chemical change has occurred while the butter was over the heat.
