Burning of the candle is both physical and chemical change. Burning of candle melts the wax and hence physical state of wax has changed from solid to liquid. Again the wax combines with the atmospheric oxygen and changes to carbon dioxide, heat and light. Thus both the changes are accompanied by the burning of the candle
is a reversible change as after the burning of a candle we can make the candle again from the wax formed as a result of burning and is also an irreversible change as the candle wick where it catches fire from can not be made back after a candle burns
