what makes the middle zone of a candle flame Luminous
Answers
A candle flame is formed because waxvaporizes on burning. ... The innermost zone, directly above the wick, containswax that has been vaporized but that is unburnt. It is the darkest zone. The middle zone is yellow and luminous because As it is an oxygen depleted zone, insufficient oxygen exists to burn all of the wax vapor. As such, partial combustion of wax takes place. The zone also contains unburnt carbon vapor. The temperature in this region is hotter than the innermost zone, but cooler than the outer zone. The outer zone is the area where the flame is the hottest and complete combustion of wax takes place. It is light blue in color and not normally visible.
