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 else can I help you with?
How many zones does and oxidising flame have?
10
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
What are the parts of a flame?
Not sure which part is which but some of them are: oxidizing reducing Not sure which part is which but some of them are: oxidizing reducing
What is the average temperature of the flame of the candle?
Depending on the wax, and the concentrations of water of oxygen in the air, somewhere between 1,200 degrees and 1,700 degrees Celsius. The heat capacity and conductivity of air and the exhaust products of combustion, however, are both very low. In practice, candle flames do not seem very hot (much like metal feels colder than wood at room temperature, though they are the same temperature). The outer core of the candle flame is light blue -- 1670 K (1400 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange and finally red. The further you reach to the center of the flame, the lower the temperature will be. The red portion is around 1070 K (800 °C). The reason there is this variation in a candle's flame color is because air convection pulls the warmer gasses upwards.
Does the blue flame on a Bunsen burner need the air hole open or shut?
It needs to be open to create the hot, blue flame that roars. If the air hole is shut, the flame will burn yellow, similar to a candle.
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.
Show diagram of candle flame zone?
The candle has 4 zones: Blue zone Dark inner zone luminous zone non-luminous zone
What are the different colors that a candle flame can exhibit?
A candle flame can exhibit various colors such as yellow, orange, and blue, depending on the temperature and the materials burning.
Is candle flame a source of light?
The flame of a candle is a source of light.
Why is a candle flame seen?
A candle flame is seen because it consists of glowing gases.
Use flame in a sentence?
The candle flame flickered in the dark room, casting shadows on the walls.
Does a candle with flame have cells?
No, a candle with a flame does not have cells. Cells are the basic structural and functional units of living organisms, and a candle is not considered a living organism. The flame on a candle is a result of the combustion of wax and a wick.
How are an animal and a candle flame alike?
well both an animal and a flame candle need oxygen to survive
What is the middle flame called?
The middle flame in a three-flame candle is often referred to as the "main" flame. It is typically larger and serves as the focal point of the candle's illumination.
Is a candle flame a living thing?
No, a candle flame is not a living thing. Living things have the ability to grow, reproduce, respond to stimuli, and maintain homeostasis, qualities that a candle flame does not possess. A candle flame is a result of a chemical reaction between the wax and oxygen, producing light and heat.
What are the benefits of using a double flame candle compared to a single flame candle?
Using a double flame candle provides more light and heat compared to a single flame candle, making it ideal for larger spaces or for creating a cozy atmosphere. Additionally, the two flames can help the candle burn more evenly and last longer.
Is a candle wick nessary?
Yes a candle wick is necessary to get the candle flame. The molten wax ascends the wick by capillary force and burns to create the flame.
