Answer:

When a candle burns, the oxygen in the air reacts and forms carbon dioxide. A new substance, the CO2 is formed. So it is a chemical change. When the candle melts, no new substance is formed and the molten wax can be again solidified and made into a candle.

The process of burning (as opposed to evaporating) is a chemical reaction, a chemical change. The wax molecules are undergoing a chemical change; they are changing into different molecules by reacting with a substance in the air. What is this substance in the air that a candle needs to burn?
