Non luminous zone is the zone of a flame which is also the hottest zone of the flame as it is mostly in contact with oxygen. It is also called invisible zone.
The luminous flame is orange or yellow in colour and it occurs when the air hole is fully closed. It is not recommended for heating as it is lesser hot, thus taking a very long time to heat things. Also, it is unsteady and it flickers. When heating with luminous flame, it will also cause the beaker to produce soot.
Luminous flame is a flame that is safe for the use of students doing an experiment. Luminous flame does take some time to heat something. Luminous flame is safe basically because it is visible since its color is yellowish-orange. When using a Bunsen Burner, to create a luminous flame, you will have to cover the hole with the collar. Luminous flame produces a lot of carbon dioxide.
On the other hand, non-luminous flame is a flame that is not so safe for the use of students doing an experiment although it takes a very short time to heat something. Non-luminous flame is not safe because it is almost invisible since its color is transparent blue. When using a Bunsen Burner, to create a non-luminous flame, you will have to uncover the hole from the collar. Non-luminous flame does not produce carbon dioxide.
A luminous flame is typically yellow in color and produces soot due to incomplete combustion. It has a lower temperature compared to a non-luminous flame and is often used in heating applications where a visible flame is desired, such as in gas stoves or lanterns.
It has an unsteady/wavy flame, is orange in colour and produces a lot of soot. It is also not as hot as a non-luminous flame.
a luminous flame is a flame that emits light and is orange-yellow in colour
The luminous flame is produced with an excess of fuel. May be yellow.
It is yellow in color

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.
Non-luminous flame should be used for heating in the because the flame is steady and produce little or no soot. Non-luminous flame is very hot thus, it is recommen- dable to use for laboratory purposes. Luminous flame is unsteady while non-lumi- nous 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.
A luminous flame is produced when a chemical reaction (such as combustion) releases energy in the form of light. The presence of solid particles or molecules in the flame can also contribute to its luminosity by emitting light as they are heated. This is different from a non-luminous flame, which does not produce visible light.

-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.

A luminous flame is produced when a chemical reaction (such as combustion) releases energy in the form of light. The presence of solid particles or molecules in the flame can also contribute to its luminosity by emitting light as they are heated. This is different from a non-luminous flame, which does not produce visible light.
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.
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.
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.
The degree of a luminous flame is 100 degree .
A luminous flame is one that emits light due to incomplete combustion of fuel. It takes longer to heat an equal amount of water using a luminous flame because a significant amount of heat energy is lost as light instead of being transferred to the water. This means less heat is available to raise the temperature of the water, resulting in a longer heating time.
