Write true or false for the following statements:

During burning of a candle only chemical change takes place.

False

Both physical and chemical changes occur during burning of a candle. There is a change in the state of wax from solid state to liquid state and from liquid state to vapour state. Change in state of the matter is a physical change.


Burning involves the process of combustion. The candle is basically a carbon containing material which combines with oxygen to give out carbon dioxide. This process is a chemical change.
