Physical Properties and Changes
• A physical property of matter can be observed or measured without changing the matter’s identity.
• Most physical changes are reversible because they do not alter the identity of the matter being changed. Physical changes only affect the matter’s form.
Your Task: Explain why each of the above would be a physical property leading to a physical change and not a chemical property leading a chemical change.
Physical Changes Examples
Aluminum foil is cut in half.
Clay is molded into a new shape.
Butter melts on warm toast.
