Answer

Brief Explanations:

A physical change is a change in which the substance's physical form changes, but its chemical composition remains the same. Ice forming and melting is a physical change as water changes between solid and liquid states without altering its chemical identity (H₂O). Burning paper is a chemical change as new substances are formed. Rusting is a chemical reaction changing iron's chemical nature. The reaction between vinegar and baking - soda is a chemical reaction producing new substances.

Answer:

ice forming and then melting back into water
