Different Zones of Candle Flame Video Lecture - Science Class 8

zones of candle-flame the substances
that vaporize during burning produce
flames in the candle the molten wax
Rises through the wick and is vaporized
during burning forming flames
different zones of candle-flame and the
features one dark zone the dark zone is
formed just around the wick of the
candle flame the melted wax moves up
with the help of capillary action
through the cotton wick and vaporizes
just around the wick creating a dark
zone there is no air present here it is
the least hot of all the zones to
luminous zones as the molten wax further
vaporizes it forms a yellowish flame
known as luminous zone the luminous zone
is moderately hot because of limited
supply of oxygen three non luminous zone
the non luminous zone is the zone of
complete combustion
it looks like an aura formed around the
candle and is almost invisible it is the
hottest zone around the candle flame the
ample presence of oxygen aids in
complete combustion for blue zone the
blue zone is another zone of incomplete
combustion found at the base of the
flame the bluish hue is formed due to
the burning of carbon monoxide that
releases carbon dioxide
