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.

Why must the size of the test flame be kept very small?
The flame test is made in nonluminous flames which are not high flames.
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.
What two flames flickers non-luminous or luminous?
A luminous flame flickers while a non-luminous flame remains steady.
What does nonluminous body mean?
Having a non-luminous body means that it is not a see-through body. Many insects have a non-luminous body. Non-luminous body also means an object that cannot reflect light.
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.
What kind of flame is non luminous?

What is luminous flame and Explain why it takes a longer time to heat equal amount of water using a luminous flame?
yellow color in a luminous flame produces soot or carbon. carbon dioxide is present in the luminous flame but when its combined with oxygen the flame is nonluminous which is in a blue color. it takes a longer time because luminous flame is cooler than the nonluminous. I only know what luminous flame is. The inner part of luminous flame is blue while the outer part of the luminous flame is yellow. It is unsteady. Yeah. Carbon Dioxide is only present in the luminous flame. When oxygen is combined with the flame, the flame will become non- luminous which is inner and outer part are blue. Hmm. Actually luminous flame's hottest part is at the bottom while non- luminous flame hottest part is at the middle and the top. That's all i know. If i know more, i will update for you. Thank you!
