Best Answer

There is a lack of oxygen in the flame itself (most probably because of the air holes in the Bunsen burner or of your burning device) this effect would create a luminous flame (better known as a yellow flame). A kind of flame that does not burn as hot as a non-luminous flame (better known as a blue flame)

When luminous flame is produced?

A non luminous flame is produced when the air valve is opened enough to allow complete combustion of the methane gas.


When is a non-luminous flame produced?

A non luminous flame is produced when the air valve is opened enough to allow complete combustion of the methane gas.

Is a luminous gas flame hot?

Yes, but not as hot as the blue one.


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.


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.


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.

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.
