Explanation:
The middle zone of a candle flame is the region where the combustion process is taking place. This region is also known as the zone of partial combustion. Here, the wax vapors are breaking down into hydrogen and carbon atoms. The hydrogen atoms react with oxygen in the air to form water vapor, while the carbon atoms react with oxygen to form carbon dioxide.
The combustion in the middle zone is incomplete, and as a result, a lot of soot is produced. The soot is visible as a black smoke that rises from the candle flame. The black smoke consists of tiny carbon particles that are too small to be seen individually.
The middle zone is hotter than the outer zone of the flame. The heat generated in the middle zone causes the wax to vaporize and rise up the wick. The heat also causes the outer zone of the flame to glow.
In summary, the middle zone of a candle flame is the region of partial combustion where the wax vapors are breaking down into hydrogen and carbon atoms. The combustion in this region is incomplete, and a lot of soot is produced. The middle zone is hotter than the outer zone of the flame and is responsible for generating the heat that causes the wax to vaporize and rise up the wick.
