Can physical and chemical changes occur together ? Illustrate your answer.

Text Solution

Verified by Experts

Yes, in some cases the physical and the chemical changes can occur together. One such example is the burning of candle. The wax present in the candle changes to liquid state. This means that the change is of physical nature. At the same time, the constituents carbon and hydrogen present in wax react with oxygen of air to form new subtances. This means that a chemical reaction or change is also taking place.
