Is non luminous flame steady or unsteady?

steady


Is a 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 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.

Characteristics of luminous flame?

It has an unsteady/wavy flame, is orange in colour and produces a lot of soot. It is also not as hot as a non-luminous flame.


What two flames flickers non-luminous or luminous?

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


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.


Should a luminous or non luminous Bunsen flame be used for heating in the laboratory and why?

A non luminous flame should be used because the flame can reach a higher temperature than a luminous flame. This means that substances will be heated faster. It also doesn't produce soot unlike a luminous flame. A nonluminous flame is also steady but a luminous flame is not.


What are the characteristics of the luminous Bunsen flame?

It is orange in colour, its flame is not very hot, it wavers and is unsteady, and it produces carbon in the form of 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!

What kind of flame is recommended for heating?

The non-luminous flame is recommended and appropriate for heating. It produces a hot and steady flame with no or little soot.


What is a luminous flame?

The luminous flame is orange or yellow in colour and it occurs when the air hole is fully closed. It is not recommended for heating as it is lesser hot, thus taking a very long time to heat things. Also, it is unsteady and it flickers. When heating with luminous flame, it will also cause the beaker to produce soot.
