Question

burning of a candle undergoes both physical and chemical change give reason to justify the statement

Answer 1

hope it helps you !!

In a burning candle, there are both physical and chemical changes. The melting of the solid wax to form liquid wax and the evaporation of liquid wax to form wax vapour are physical changes. The burning of the wax vapour is a chemical change. The wax vapour reacts with oxygen in the air to form new substances including carbon dioxide and ash.

Answer 2

Answer:

When a candle burns, the wax melts which is a physical change as there is no formation of a new substance. Burning of candle releases carbon dioxide and water vapour which is a chemical change as entirely new substances are formed.
