its both because when the candle burns it melts and it's height gets shortened and it changes to a new substance when the evaporation of liquid wax to solid wax occurs

The physical change occurs when the heat displaces the bonds that solidify the wax. Upon cooling, the wax is able to form the bond again . 


in chemical change  the heat (fire) consumes the oxygen and fuels the flame. This then leads to the production and emission of carbon dioxide from the flame.
