Answer 2

Answer:

A flame consists of three zones

i) innermost zone :- it is a dark or black coloured zone. it consists of hot unburnt vapors of combustible material. it is the least hot part of the flame.

ii) middle zone :- it is the bright and Luminous zone. it produces a moderate temperature. here, partial combustion of the fuel takes place.

iii) outermost zone :- it is non luminous zone. here complete combustion of the fuel takes place because there is plenty of air around it. it has the highest temperature in the flame that is it is the hottest part of the flame.
