1. Melting ice: Solid ice turning into liquid water. 2. Boiling water: Liquid water converting to steam. 3. Cutting paper: Changing the size and shape of paper without altering its chemical structure. 4. Dissolving sugar in water: Sugar particles dispersing in water without a chemical reaction. 5. Freezing juice: Liquid juice turning into a solid as it is frozen.** These examples involve changes in form or state but do not alter the substance's chemical identity.
