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 are the regions of the Bunsen burner yellow flame?
The yellow flame of a Bunsen burner consists of three distinct regions: the inner cone, the outer cone, and the luminous zone. The inner cone is the hottest part, where complete combustion occurs, producing a blue flame. The outer cone surrounds the inner cone and indicates incomplete combustion, resulting in a cooler temperature and the yellow coloration. The luminous zone is the area where unburned carbon particles are present, giving the flame its yellow appearance due to incandescence.
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.

The candle has 4 zones: Blue zone Dark inner zone luminous zone non-luminous zone
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.
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
Which zone of a candle flame gives us light?
The light from a candle flame primarily comes from the outer zone, known as the luminous zone or outer envelope. In this region, the temperature is high enough for incomplete combustion to occur, producing incandescent soot particles that emit visible light. The inner zone, or non-luminous zone, primarily produces heat and is less bright due to more complete combustion.
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 dark zone and non luminous zone are considered as the most polluting zones of a candle flame?
The dark zone and non-luminous zone of a candle flame are considered the most polluting because they contain incomplete combustion products. In the dark zone, where the flame is cooler and lacks sufficient oxygen, carbon particles and soot are formed due to incomplete combustion of the wax. The non-luminous zone, while hotter, still produces volatile organic compounds and other pollutants as the wax continues to burn inefficiently. These areas contribute to air pollution and can release harmful substances into the environment.

what are the two most polluting zones of a candle flame?
The two most polluting zones of a candle flame are the bright yellow outer zone, which contains unburned soot particles, and the dark zone close to the wick, which contains partially burned carbon compounds. These zones contribute to the production of pollutants such as carbon monoxide and particulate matter.
What zone of flame a gold smith use for melting gold or silver?
Because it is the hottest zone of a candle 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.
