Non luminous zone or zone of complete combustion?
define luminous zone of flame
What is the meaning of non luminous flames?
The non luminous flame is hot flame; the fuel is mixed with more oxygen.
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.
What is the hottest part of the fire called?
non luminous zone
Definition of luminous and non-luminous sources of light?
what is luminous, non luminous and illuminous source of light.
Non luminous zone or zone of complete combustion?
define luminous zone of flame
Show diagram of candle flame zone?

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 is the hottest part of the fire called?
non luminous zone
Why is middle zone of the candle called luminous zone?
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
Characteristics of luminous flame?
Non luminous zone is the zone of a flame which is also the hottest zone of the flame as it is mostly in contact with oxygen. It is also called invisible zone.
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.
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.
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
Is a volcano erupting luminous or non luminous?
It is luminous
