Why is a blue flame preferred in laboratory?

the nonluminous (blue) flame is preffered because it is much hotter and more controllable/steady


Which is better the luminous or non-luminous flame?

Non-luminous flame is hotter and burn more efficiently than luminous flame as it burn all the carbon atoms. Plus, luminous flame produces soot.


What is a non-luminous flame?

non-luminous flame burns hotter than a luminous flame. It sometimes happen when the air hole in the Bunsen burner is open. Non- luminous flame is actually all blue in colour. And it is also hotter than Luminous flame. I will update if i know more. Thanks! By helpingppl

Why is the non-luminous blue flame preferred over the luminous yellow flame in the laboratory?

Non-luminous flame is hotter and burn more efficiently than luminous flame as it burn all the carbon atoms. Plus, luminous flame produces soot


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!

Why the luminous flame is less desirable than the non-luminous flame as asource of heat in the laboratory?

The primary factor is that the blue flame (non-luminous) is hotter. This is due to more oxygen being available for combustion. the yellow falme (luminous) lacks oxygen and is therefore an example of incomplete combustion, this causes it to lease carbon residue on the apparatus exposed to it -which is hard to clean off.


Difference between luminous flame and non luminous flame?

hmm, the main difference... one produces *visible* light, the other does not :P A non-luminous flame is blue in color, hardly visible, less wavy and hotter than a luminous flame. A luminous flame is not as hot, visible, orange in color, and wavy. A luminous flame is most used in experiments because it is less wavy and you have more control of it...


Why non luminous flame is hotter?

The laboratory gases undergo complete combustion hence producing more heat.


Would the sun be more luminous if it were hotter?

Yes luminous actually for a star to get hotter.


Why does the non-luminous flame produce more heat than the luminous flame?

because luminous object loss some energy in the form of flame


What are the advantage of using the non luminous flame?

The advantage of using non-luminous flame is the production of a higher amount of energy. Non-luminous flame burns more efficiently compared to luminous flame.
