Solution

Hi,

Burning of 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 atmosphere oxygen and changes to carbon dioxide, heat and light.

Thus both the changes are accompanied in the burning of candle.
