Heya...
Here is your answer ----
Burning of candle is both physical and chemical change. During the burning of a candle, two changes are taking place, that are, melting of wax, and, burning of the thread present inside the wax. Burning og wax, as we know, is a physical change as the wax can be moulded back into its original shape. But, burning of thread, or, burning of anything, is always a Chemical change as it cannot be reversed. So, burning of candle is both physical and chemical change. The wax can be reused because it is not burnt, it has melted.
