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.

Which flame represents complete combustion?
Non-luminous flame
Which bunsen burner luminous or non luminous flame used in laboratory and why?
A non-luminous flame is typically used in laboratory settings when using a Bunsen burner. This flame produces a more controlled and homogeneous heat source, making it ideal for processes like heating, sterilizing, and combustion analysis. The non-luminous flame also produces less soot and is more energy efficient compared to a luminous flame.
Which is better for cooking luminous or non-lominous flame?
For cooking, a non-luminous flame is generally better than a luminous flame. A non-luminous flame produces higher temperatures and more efficient combustion, resulting in faster and more even cooking. Luminous flames, on the other hand, are typically cooler and can leave soot on cookware, which may affect the taste and appearance of the food.
Why is non luminous blue flame preferred over the luminous yellow flame in the laboratory?
blue flame is more important for laboratory procedures since it's also known as the reducing zone of the flame in which the tip of the blue flame has the highest temperature. and thank you , a Dental student ;D
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 luminous?
Yes, a candle flame is considered luminous because it emits light by converting chemical energy into heat and light energy. This process is known as combustion, which produces a visible glow that we perceive as light.
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.
Is the candle flame that is seen luminous?
yes
Show diagram of candle flame zone?
The candle has 4 zones: Blue zone Dark inner zone luminous zone 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
Is a burning candle luminous?
Yes, a burning candle is luminous because it produces its own light through the process of combustion. The flame emits light and heat as a result of the energy released during the burning of the candle wax.
What two flames flickers non-luminous or luminous?
The two flames that flicker both non-luminous and luminous are a candle flame and a gas stove flame. When burning normally, these flames emit light due to combustion. However, if they are disturbed or lack sufficient oxygen, they can flicker and may become non-luminous.
Is sooty flame a luminous or non luminous?
A sooty flame is typically considered a non-luminous flame because it does not produce significant visible light. It appears dark or dim due to the presence of unburned carbon particles (soot) in the flame.
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.
Why is a burning candle luminous?
A burning candle is luminous because the combustion of the candle's wax produces heat, which vaporizes the wax into gas. This vapor then ignites, creating a flame that emits light as a result of the high temperatures involved. The flame generates light across a spectrum, including visible light, due to the excitation of gas molecules and the production of incandescence. Consequently, the light we see is a combination of thermal radiation from the hot gases and the glowing particles in the flame.
Should a luminous or non luminous Bunsen flame be used for heating in the laboratory and why?
Non-luminous flame should be used for heating in the laboratory because the flame is steady and produce little or no soot.Non-luminous flame is very hot thus, it is recommendable to use for laboratory purposes.Luminous flame is unsteady while non-luminous flame is steady.Another reason of using non-luminous flame because the flame of non-luminous is blue, and not visible unlike the luminous flame which is yellow in colour and visible.
What is the difference between luminous and non luminous?
-A non-luminous flame is when the air hole of the Bunsen burner is closed but a luminous flame is produced when the air hole is opened.-A luminous flame has an outer of orange colour and an inner of blue. A non-luminous flame has an outer of blue and an inner of orange.-A luminous flame produces soot while a non-luminous does not produce soot.-A luminous flame is weak and unsteady. A non-luminous flame is strong and steady.-A non-luminous flame is very hot while a luminous flame is not too hot.
