Burning of a candle is a/an
Open in App
Solution
The correct option is B irreversible
When we light a candle, the wax starts melting resulting into evolution of gases. We cannot get back the candle from these gases. Such kind of a change in which the substance cannot be brought back into its original form is called an irreversible change.
Also, the candle needs to be lighted by a human. Hence it is not a natural change.
