Solution

Dear student

Burning of candle exhibits both physical and chemical change.
Physical change can be seen prominently as candle burns wax starts melting and size of candle reduces.
Chemical change- Due to the heat produced by the flame, the wax vaporizes. This wax vapour which is near to flame burns and gives new substances like Carbon Dioxide, Carbon soot, water vapours, heat and light.

Physical change is a reversible change and chemical change is irreversible.
