Question

how will you differentiate burning of candel as - physical or chemical change​

Answer 1

Answer:

Physical change

Explanation:

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:

Burning of candle is a chemical change whereas melting of wax is physical change since the change is temporary, reversible and no new products are formed
