Answer 2

Yes, burning of a candle is a chemical change as well as physical change, this is explained as follows:
It can be stated as a physical change since the melted wax solidifies on the surface of the candle and regains its physical properties.(not considering its shape)

It can also be addressed as a chemical change since the burning of the candle produces carbon dioxide and water vapour which are the new products formed,different from the candle wax chemically and physically.
