A friend tells you that's after a candle burn there is less matter than before the flame was lit is your friend correct explain why or why not

See explanation

Explanation:

The law of conservation of matter states that "matter cannot be created or destroyed. In a physical change, substances can change form, but the total mass remains the same."(Virginia)

Hence, the quantity of matter present before and after the candle burn must remain the same in accordance with this law stated above.

Hence, my friend was not correct.
