What are the 4 zones of candle flame?

What are the 4 zones of candle flame?

Candle Flame Different Zones

• The first zone is called the Outer zone.
• The second zone is called the Middle zone.
• The third zone is called as Inner zone.

What are the different zones of flame?

The flame of the candle has three zones, the outer zone is blue, the middle zone is yellow and the inner zone is black.

What are the 3 zones of a candle flame?

The outer zone is blue, the middle zone is yellow and the inner zone is black.

Which zone of candle flame is hottest?

Due to complete combustion, the outer zone is blue in color. This zone is the hottest in temperature when compared to the other zones. This blue colored zone is the non luminous part of the flame.

What are the different zones of a candle flame Class 8?

The three zones are as follows:

• Outer zone.
• Middle zone.
• Inner zone.

Which zone gives of light?

Luminous zone consists of a partial combustion with liberation of heat in large amount and thus light is emitted.

Which is the coldest part of a candle flame?

The Innermost zone of a flame is dark or black:It consist of hot,unburnt vapours of the combustible material.It is the least hot part of the flame.It is the coldest part of the flame.

What is blue zone in flame?

In LPG the blue zone represents the zone of complete combustion of the fuel. So, the amount of soot decreases with increasing oxygen supply and the temperature is highest as high heat is released. This zone is said to be the hottest in temperature when compared to the other zones.

What is the middle zone of a burning candle known as Why?

Answer: Explanation:The middle zone of the candle flame is luminous because there is not enough air for complete burning of the wax vapour. The incomplete burning of wax vapour produces carbon particles and carbon monoxide.

Which zone of a candle flame gives light?

The luminous zone of a candle flame is the zone of incomplete combustion. The wax vapours do not burn completely, since the supply of oxygen is inadequate in this zone. When an object is placed over this zone, it releases black soot and other residues. The carbon particles in it, glow, emitting a yellow light.

Which of the following zone produces light in the candle flame?

The incomplete combustion of wax vapour produces carbon particles. These unburnt carbon particles get heated up and start glowing. These glowing carbon particles make the flame luminous. Thus, the central zone of the candle flame is luminous due to the incomplete combustion temperature.
