Identifying physical and chemical changes.matter has both physical and chemical properties and can undergo physical or chemical changes. physical properties are those that a substance displays without changing its composition, whereas chemical properties are evident only during a chemical change (also called a chemical reaction). in contrast, when a substance undergoes a physical change, it may change appearance, but not its composition.part a: classify each of the changes as a physical change or a chemical change.part b: classify each of the properties as a physical property or a chemical property.
