Question

explain breifly zones of candle. if you explain briefly i will mark you as brainliest

Answer 1

1) The Innermost zone of a flame is dark or black:It consist of hot,unburnt vapours of the combustible material.It is the least hot part of the flame.

2)The middle zone of a flame is yellow:It is bright and luminous.The fuel vapours burn partially in the middle zone because there is not enough air of burning in this zone.The partial burning of fuel in the middle zone produces carbon particles.These carbon particles then leave the flame as smoke and soot.It has moderate temperature.

3)The outer zone of a flame is blue:It is a non-luminous zone.In this zone,complete combustion of the fuel takes place because there is plenty of air around it.The outermost zone has the highest temperature in the flame.It is the hottest part of the flame.It is quite thin as compared to middle zone.

Answer 2

The outermost zone is hottest of all and is blue in colour and this is due to complete combustion. It is also the non luminous part of the flame .
The middle zone of the flame is moderately hot and is yellow in colour. Over here partial combustion of fuel takes place and it is also the bright part of the flame.
Hope it helps
