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.
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.
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.
Is a candle flame seen because it is luminous?
There are different types of energy. In this case, the energy apart from radiant heat is giving off energy in the visible range, ~400-800 nm wavelength. That's why you can see it.
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 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.
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.
What is the degree of hotness of luminous flame?
The degree of a luminous flame is 100 degree .
Does a candle light reflect light or is it luminous?
It is luminous.
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
Why is it advisable to turn a luminous flame to a non luminous flame when the flame is not in use?
Turning a luminous flame to a non-luminous flame when not in use conserves fuel because non-luminous flames burn more efficiently. A non-luminous flame produces less soot and smoke, making it safer and better for indoor air quality.
Is non luminous flame steady or unsteady?
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.
