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.

What happen to the charcoal if you spray to the non-luminous flame?

the fire of the non-luminous flame willl haeve a great spark to the flame


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.


How does luminous flame exist?

because of the yellow flame, yellow is a bright coulor........... Scientific term......... The collar is closed to get luminous flame and collar open to get non- luminous flame....

-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.

When the Bunsen burner is on but no experiment is being carried out why is it advisable to set it to the luminous flame?

So you don't burn yourself. If it's on and you're not paying attention to it, a luminous flame is easily glimpsed in your peripheral vision. If the flame was non-luminous, it's much harder to detect and causes a greater risk. the non-luminous flame also burns much hotter.
