Answer 1

Answer:

Melting of wax is temporary and wax can settle again on cooling and turns into a solid. Hence, the change is only physical and the state of matter changes. Burning of the candle is permanent because once it is burnt it cannot be converted into the candle. A new product is also formed with a composition different from candle. Hence it is a chemical change.
