Heating is an increase in energy in a substance. Heat is merely the measure of excitation of atoms or molecules, and as such heating a substance does not usually change anything chemically, unless you have a very unstable chemical (E.g. Argon Fluoride doesn't function above -233 Celsius.

∙ 13y agoThis is because when you burn butter, the butter turns into another substance and you can not bring the butter back to its original state. When you are melting butter, the substance is still the same they are just farther apart. You can also bring it back to its original state by cooling it or freezing it
