Question

2 - When a candle burns, both physical and chemical changes occur. What

are these changes​

Answer 1

Answer:

Physical Changes: On heating, candle wax gets melted. Since it again turns into solid wax on cooling. So, the melting of wax and vapourisation of melted wax are physical changes.

Chemical Changes : The wax near flame burns and gives new substances like carbon dioxide, carbon soot, water vapour, heat and light.

Answer 2

Answer:

physical change = solid wax into liquid wax

chemical change = burning of chemicals
