Answer 2

Hey mate!!!

Your answer is non luminous zone.


Flame has three parts-

Bottom zone- Blue zone
Luminous zone- Middle zone
Non luminous zone - outer zone.

The blue zone is due to the complete combustion and hence it is the least hot.

Middle zone is the yellow zone and is moderately hot.

The non luminous zone is the most hot.



Hope it helps dear friend ☺️✌️✌️✌️✌️
