Is burning a candle a chemical or physical change
Asked by admin @ in Chemistry viewed by 367 People
Burning of candle is a chemical change whereas melting of candle is physical change. Why?
Answered by admin @
Hey!
When a candle burns, the oxygen in the air reacts and forms carbon dioxide. A new substance, the CO2 is formed. So it is a chemical change.
When the candle melts, no new substance is formed and the molten wax can be again solidified and made into a candle.which means it is a reversible change.
So we can say the burning of a candle is both a chemical as well as a physical change.
Hope it helps...
