Question

define middle zone of candle​

Answer 1

Middle zone: The middle zone also known as luminous zone is the zone which is moderately hot with limited oxygen supply. Hence, the fuel vapours burn partially and produce carbon particles. These particles then leave the flame as smoke and soot. This zone is the major part of the flame

Answer 2

Explanation:

There are three zones in flame, viz. outer zone, middle zone and inner zone. Outer Zone: This zone is blue in colour. It is the hottest part of the flame, because complete combustion takes place in this zone.
