What is the forms flame of candle?

Posted by Abhinav Chaudhary 7 years, 6 months ago

CBSE > Class 08 > Science

1 answers

Meghna Thapar 5 years, 7 months ago

There are three zones or parts of a flame – innermost, middle and outer zone.

Innermost zone: The innermost zone of a flame is dark or black. It consists of hot, unburnt vapours of the combustible material (candle). It is the least hot part of the flame.
Middle zone: The middle zone of a flame is yellow. It is bright and luminous. In it the fuel vapours burn partially because there is not enough air so it produces carbon particles which become white hot and emit light. This zone is the major part of a candle flame.
Outer zone: It is non-luminous zone. It is the outer zone of a flame where complete combustion of the fuel takes place because there is plenty of air around it. It has the highest temperature in the flame.
