Answer 1

Answer:

here is your answer ✧✧

Burning of a candle is a chemical change .

Reason:

when a candle is burnt in air, the mass of the product is increased due to atmospheric oxygen which combines with the carbon and hydrogen of the candle wax during burning to produce water vapour and carbon dioxide. So, we can say that it is a chemical change.

Answer 2

when a candle is lit,the wax melts and turn into liquid and turns into liquid state. As some of the molten wax drops on the floor it solidifies again. Therefore is a physical change.

Simultaneously most of the molten wax rises up the wick turns into vapour and burns with the flame. Two new substances are formed water vapour and carbon dioxide. Candle becomes smaller and smaller. this is a chemical change.

Burning of a candle is example of simultaneous physical and chemical change.
