- non luminous zone: outermost not fully visible complete combustion zone
- luminous zone : incomplete combustion zone pale yellow in color
- dark zone : no combustion dark in color coldest zone
- blue zone : bottom zone blue in color carbon monoxide wax vapors

Different zones of candle flames?
These are the 4 zones of a candle flame from outermost to innermost A Non luminous zone . or zone of complete combustion b. Luminous zone or zone of incomplete combustion c. Dark zone or zone of no combustion d. Blue zone
Why the outer layer of flame of candle is more hotter than the inner layer?
burning of a substance depends upon the availability of oxygen to it. as the supply of oxygen to outermost part is greatest complete combustion takes and a blue colored flame is produced! hence outermost layer is hottest
What are the different zones of candle flame?
The candle flame has 4 zones from innermost to outermost: 1)Blue zone: It is near the base of the flame. Here the fresh air rapidly mixes with was vapour formed from the molten wax.A part of wax vapour completely burns and gives rise to blue flame. 2)Dark inner zone: This part consists of unburnt wax vapour given off by molten wax.It is the coldest part of the flame It is dark because of of decomposed carbon particles. 3) Luminous zone: In this zone partial combustion takes place with liberation of a lot of heat. This zone is hotter than the dark inner zone. 4) Non luminous zone:It is a zone were complete combustion takes placeIt is hottest part of the flame and is hardly visible.
Is candle flame a source of light?
The flame of a candle is a source of light.
What happens during a melting candle?
when a candle is lighted ; this is what happens : the solid wax melts and rises up the wick. The wax vapours react with oxygen to burn as a flame. The candle starts melting. This is a physical change. while observing the candle flame we see that the candle has 3 zones. Non - Luminous zone is the innermost zone. It appears as a dark zone and is the coldest part of the candle flame due to less oxygen. Then comes the Luminous zone , it is yellow and opaque. The glowing of carbon particles cause the flame to look yellow and emit light. Then , Invisible zone - it is the outermost zone of the candle flame. it is the hottest zone and cannot be seen with naked eye. Combustion reaction comes to completion here and carbon changes into carbon dioxide.
Why is a candle flame seen?
A candle flame is seen because it consists of glowing gases.
Why innermost zone of a flame is less hot?
the inner most zone of a flame is less hot because it has unburnt carbon particals and combustion does not take place .thats why innermost zone of flame is less hot
How are an animal and a candle flame alike?
well both an animal and a flame candle need oxygen to survive
Use flame in a sentence?
