explain the zones of a candle flame
Answers
Dark zone,luminous zone,non luminous zone and blue zone
1.the innermost zone : it is the zone which is formed just around the wick of the candle as it burns. it is also known as the dark zone of the flame . it consist of hot unburnt vapors of the combustible material. there is no air present here. it is the least hot of all zones
2. middle zone: also known as luminous zone which has moderate heat with limited oxygen supply hence, the fuel vapors burn partially and produce carbon particles .. these particles then leave the flame as smoke and soot . this zone is the major part of the zone . the color of this zone is yellow
3. the outermost zone: also known as non- luminous zone is the zone of complete combustion . the ample presence of oxygen aids in complete combustion . it is the hottest zone of the candle flame and does not produce much light . it is blue color
