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.


Suggest two reasons why a luminous flame is not used as a source of heat in a laboratory experiment?

It produces more heat. It does not produce soot that would stain the laboratory apparatus.


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.


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.


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.

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 type of flame should use in laboratory luminous or non luminous?

Non- luminous flame should be used as it is steady and produces little or no soot.


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

Why non luminous flame is hotter?

The laboratory gases undergo complete combustion hence producing more heat.


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 kind of flame the best used in all laboratory?

The best flame for use in a laboratory is typically a blue flame produced by a Bunsen burner. This flame provides a consistent and controllable heat source with a high temperature suitable for a wide range of laboratory tasks.
