Which flame represents complete combustion?
Non-luminous flame
What is the meaning of non luminous flames?
Non-luminous flames are flames that do not emit visible light. These flames occur when there is not enough oxygen available for complete combustion to take place. As a result, the flame appears mostly blue or invisible to the naked eye.
What is the hottest part of the fire called?
The hottest part of a fire is called the flame. Flames are the visible, luminous gas that is generated by the combustion process, and they represent the most intense heat and energy.
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.
Sketch and label of different flame region coming from Bunsen burner?
A Bunsen burner flame typically consists of three regions: a non-luminous inner blue flame at the base, a luminous yellow flame surrounding the inner blue flame, and an invisible outer cone of hot air. The inner blue flame is the hottest part of the flame and is commonly used for heating purposes. The outer cone provides a secondary combustion zone for complete combustion of the gas.
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
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
What are the various zones of a candle flame?
The various zones of a candle flame are the dark zone, the blue zone (inner cone), the luminous zone (middle zone), and the non-luminous zone (outer zone). In the dark zone, the wick is vaporized and breaks down into fuel molecules. The blue zone is where complete combustion occurs due to a sufficient oxygen supply, while the luminous zone emits light due to incomplete combustion of fuel. The non-luminous zone consists of unburned fuel and soot particles.
Which flame represents complete combustion?
Non-luminous flame
What is the meaning of non luminous flames?
Non-luminous flames are flames that do not emit visible light. These flames occur when there is not enough oxygen available for complete combustion to take place. As a result, the flame appears mostly blue or invisible to the naked eye.
When is a non luminous flame produced?
A non luminous flame is produced when the air valve is opened enough to allow complete combustion of the methane gas.
When is a non-luminous flame produced?
A non luminous flame is produced when the air valve is opened enough to allow complete combustion of the methane gas.
How does a non-luminous flame exist?
The non-luminous fire exist when there is a complete combustion or complete burning process. It happens when there is more than the enough oxygen in the surroundings or in the place where the process will happen.
When luminous flame is produced?
A non luminous flame is produced when the air valve is opened enough to allow complete combustion of the methane gas.
Why non luminous flame is hotter?
The laboratory gases undergo complete combustion hence producing more heat.
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.
When is flame produced?
A non luminous flame is produced when the air valve is opened enough to allow complete combustion of the methane gas.
