Answer: False
Step-by-step explanation:
When substances that are different from the starting substances form, a chemical change has occurred, not a physical change. A physical change refers to a change in the physical properties of a substance, such as shape, size, or phase, without altering the chemical composition. Examples of physical changes include melting, freezing, boiling, or dissolving. So, when different substances are formed, it indicates a chemical change, not a physical change.
