ans :-
1)Melting of wax is a physical change where the physical state of wax changes from solid to liquid. The melted wax that solidifies, can be changed to a liquid state on heating
2)burning of candle is chemical change
3)the size of the candle reduces bcoz it's irreversible
4)this change involves chemical properties and thus can not reversed
