hy friend, here is your answer
when the candle burns ,both chemical and physical changes occur;
1. physical change- when candle is lit , the heat of flame melts the solid wax into liquid wax. this signifies the physical change
2. chemical change- the wax acts as a fuel when we light the candle and is basically a chemical substance called carbon. the carbon combines with oxygen to form another chemical substance called carbon dioxide . also the unburnt carbon is deposited as a black substance called soot. this signifies a chemical change
