Answer

Brief Explanations:

Physical changes do not change the chemical composition of a substance. Freezing water is a phase - change (solidification) without altering water's chemical identity. Cutting paper only changes its physical form. Mixing water and acetone is a physical combination without a chemical reaction. Burning wood is a chemical reaction (combustion), and iron rusting is a chemical reaction (oxidation).

Answer:

  • freezing water
  • cutting paper
  • mixing water and acetone
