luminous flames are those which throw or Emmit bright light of great intensity......but non luminous flames are those which just glow and do not emmit light of such great intensity................

it should not be misunderstood with candle ......and coal........as one emits flame and the other does knot's as there is no flame......there is no point of luminous or non luminous

A luminous body is a natural body which gives out light like sun,star,light bulb etc....

From an organic chemistry view, a luminous flame, is a yellow and bright flame, that comes from organic compounds with loss of hydrogen, resulting in incomplete combustion, very different from a non-luminous flame, that is observed with propane, butane, methanol or ethanol flames, that can have a light blue color, but not a bright yellow flame. This non-luminous can be observed in a complete combustion (so it forms only water and carbon dioxide).

This luminous combustion can be seen when a car or a gas station explodes or in petrochemical fires...

What are the advantages of using a non-luminous flame?

Non- Luminous can burn efficiently because luminous flames don't burn as efficiently as non-luminous ones, they don't produce as much energy. This means that the non-luminous flames have a lot more energy than luminous ones, and their flames are actually hotter. This is why the luminous ones look yellow and the non-luminous ones look blue. Hotter flames burn blue and (relatively) cooler ones burn yellow.


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.


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.


What are the disadvantages of luminous flame?

A luminous flame is not suitable for heating as it gives out soot (A black powdery or flaky substance consisting largely of amorphous carbon, produced by the incomplete burning of organic matter).


What are the two kinds of flames produced by Bunsen burner?

The two types of flames a Bunsen burner can produce are a luminous, yellow flame and a "roaring" blue flame. The blue flame is much hotter than the yellow flame.

What two flames flickers non-luminous or luminous?

A luminous flame flickers while a non-luminous flame remains steady.


Properties of luminous and non-luminous flames?

luminous flames have a bluish to violet color and it means that the system is given enough oxygen for the reaction. Luminous flames will not produce soot. non luminous flames are orange, red, and yellow much like your everyday campfire but this system is not given enough oxygen therefore produce soot.

What kind of flame is non luminous?

No-luminous flames, with a blue color, are formed when the oxygen is in excess.


Is a luminous flame a hot flame?

All flames are hot

What is the meaning of non luminous flames?

The non luminous flame is hot flame; the fuel is mixed with more oxygen.

Why is a Bunsen burner not used for heating when the air hole is closed?

When the air hole is closed, the flame is a luminous flame. This flame is not ideal for heating for the following reasons: it is not as hot as the non-luminous flame it is very unstable it produces a lot of soot thus, only non-luminous flames (the blue one) is ideal for heating. :)


Why is it advisable to put off a non luminous flame when not in use?

Non- Luminous can burn efficiently because luminous flames don't burn as efficiently as non-luminous ones, they don't produce as much energy. This means that the non-luminous flames have a lot more energy than luminous ones, and their flames are actually hotter. This is why the luminous ones look yellow and the non-luminous ones look blue.
