  • C. Melting wax
  • D. More than one of the above
  • E. None of the above

Correct Answer (Detailed Explanation is Below)

B. Burning of paper

Detailed Explanation

Burning of paper is a chemical change because new substances such as carbon dioxide, water vapour and ash are produced. Chemical changes are generally accompanied by changes in composition and may involve heat, light, gas formation or colour change. Physical changes, such as cutting paper or melting wax, do not normally produce a new chemical substance.
