Is the temperature of a luminous flame greater ot less than that of a nonluminous flame?
The yellow color in a luminous flame is basically the black-body
emission from hot particles of soot in the flame. they are hot, and
they glow like the filament of a light bulb.
In a blue flame, there are no particles of soot to give that
incandescent radiation. Instead, the main color you see is blue
emission from the high-energy C2 molecule.

Is the temperature of a luminous flame greater or less than that of a nonluminous flame?
a non-luminous flame- when the air hole of the Bunsen Burner is open"when the air hole is open, more oxygen can enter the burner; therefore, hotter flame will be produced."its color is transparent or blueBlue flames are the hottest flamesa luminous flame is produced when the air hole is closed.."if the air hole is closed, oxygen cannot enter the burner; therefore, least hotter because the combustion is not fully complete with least oxygenA luminous flame has an outer of orange color and an inner of blue.Luminous flames emits more light than non-luminous flames.three things to produce flame1.fuel2.oxygen3.friction or source of sparkLuminous objects emit light. The sun is luminous; the moon is non-luminous.
Why the dominant color of a nonluminous flame on a Bunsen burner blue?
The dominant color of a nonluminous flame on a Bunsen burner is blue. Whereas, the dominant color of a luminous flame on a Bunsen burner is orange.
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 luminous flame and Explain why it takes a longer time to heat equal amount of water using a luminous flame?
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.
Which portion of the luminous flame is the coolest?
For a Bunsen burner the lowest temperature is in the extreme lower part of the flame.
Why a luminous flame is not used as a source of heat in a laboratory experiment?
A luminous flame produces soot, which can contaminate the experiment or react with chemicals being used. In addition, the temperature of a luminous flame is not as high or consistent as a non-luminous flame, making it less suitable for precise heating applications in a laboratory setting.
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 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 .
Characteristics of luminous flame?
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.
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.
