the wax burning is a physical change (vapourisation) followed by a chemical change (burning). The wick only undergoes a chemical change (burning).

Explanation:When you light a candle, wax near the wick melts into a liquid. The heat of the flame vaporizes the wax molecules and they react with the oxygen in the air. As wax is consumed, capillary action draws more liquid wax along the wick. ... Both light and heat are radiated in all directions from a candle flame.
