partial combustion takes place here and wax vapour start burning with a yellowwish flame . this region of candle flame is moderately hot. so it is called as the luminous zone

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.
What is neritic zone also called as?
Continental Shelf
What kind of fish live in the Near-Shore Zone?
The specific area in the ocean which is touching or close to land is called neratic zone .
What are the three main layers of the ocean?
he Epipelagic Zone is the first layer of the ocean. It's the zone that extends from the surface to 200 meters in depth. In this zone there is the most light and where there is sun there is heat. This is also the most clear zone.The Mesopelagic Zone is the second zone of the ocean layers. Extending from 200 meters to a 1000 meters. In this zone there isn't almost any sunlight that penetrates these depths. It's also called the Twilight zone or the Middwater zone, most of the deep sea fishes are living in this zone.The Bathypelagic Zone is also called the dark zone. In this zone there isn't any sunlight, but you can find light that is produced by deep sea animals like the Firefly Squid or the Vampire Squid. This zone extends from 1000 meters to 4000 meters where the pressure is so high that only a few deep sea animals can handle the pressure. The animals that live on these depths are mostly specially adapted creatures and they have a very different appearance then normal fishes.The Abyssopelagic Zone, this zone is very cold and it almost doesn't contain any lifeform. It's also called the abyss, what actually means no bottom in Greek. The animals that live here are mostly invertible like tiny sea animals. This zone extends from 4000 meters to 6000 meters! The pressure is too high for many deep sea animals.The Hadalpelagic Zone or Hadal zone, the last zone of the ocean layers extends from 6000 meters to the deepest bottoms of the oceans! The deepest spot can be found at the Mariana Trench of the coast of Japan that has a depth of more then 10.900 meters. The pressure here is just amazing and still there are creatures like the Viperfish and the Angler fish that can live on these depths. Animals that live on these depths die if they go to a zone with a lower pression.
What are the three main latitudes of the earth?
The 3 latitude zones: High latitude zone-poop The high latitude zone is cold. Middle latitude zone- The middles latitude zone is hot and cold. Low latitude zone- The low latitude zone is hot.

what are the two most polluting zones of a candle flame?
the blue zone and the non - luminous zone of a candle flame are the two most polluting zones.
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
What are the various zones of a candle flame?
innermost zone outer zone middle zone
What is the meaning of non luminous flames?
The non luminous flame is hot flame; the fuel is mixed with more oxygen.
What is the hottest part of the fire called?
non luminous zone
Non luminous zone or zone of complete combustion?
define luminous zone of flame

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.
What zone of flame a gold smith use for melting gold or silver?
Because it is the hottest zone of a candle flame.
Description the 4 zones of a candle flame from outermost to innermost?
non luminous zone: outermost not fully visible complete combustion zoneluminous zone : incomplete combustion zone pale yellow in colordark zone : no combustion dark in color coldest zoneblue zone : bottom zone blue in color carbon monoxide wax vapors
Why does a non luminous zone produce less residue as compared to a luminous one?
In the luminous zone of a flame solids such as carbon are produced because there is only a small supply of oxygen to burn the fuel. In the non-luminous zone there is more oxygen and the fuel is completely oxidised to gases such as carbon dioxide.
