Reactions that are not chemical reactions are physical reactions. These reactions involve a change in only the physical state of an element, not its chemical properties. Thus, physical changes include freezing, condensation, sublimation, hammering a metal into a sheet, cutting sodium metal, etc.
Chemical reactions are of course chemical changes.
metalbolism
Pasteurization involve chemical reactions.
All physical and chemical reactions , see text book from A to z .
