Answer 1

Colors tell us the temperature of theflame. The outermost zone is the hottest among all zones and is blue in color, and this is due to complete combustion. It is the non-luminous part of the flame. The middle zone of the candle flame is moderately hot and is yellow in color, and partial combustion of fuel takes place.
