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.
Why is it safer to close the air holes to obtain a luminous flame?
When the air hole on a Bunsen burner is closed, air is excluded, so the flame becomes a yellowish candle-like flame.
Is sooty flame a luminous or non luminous?
luminous
What two flames flickers non-luminous or luminous?
A luminous flame flickers while a non-luminous flame remains steady.
Which portion of non luminous flame is the hottest?
The hottest portion of the non luminous flame is the inner cone (light blue center).
Is the candle flame that is seen luminous?
yes
Show diagram of candle flame zone?
The candle has 4 zones: Blue zone Dark inner zone luminous zone non-luminous zone
what are the two most polluting zones of a candle flame?
the blue zone and the non - luminous zone of a candle flame are the two most polluting zones.
Why is middle zone of the candle called luminous zone?
partial combustion takes place here and wax vapour start burning with a yellowwish flame . this region of candle flame is moderately hot. so it is called as the luminous zone

Should a luminous or non luminous Bunsen flame be used for heating in the laboratory and why?
Non-luminous flame should be used for heating in the laboratory because the flame is steady and produce little or no soot.Non-luminous flame is very hot thus, it is recommendable to use for laboratory purposes.Luminous flame is unsteady while non-luminous 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.
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.
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....
Is sooty flame a luminous or non luminous?
luminous
Is a burning candle luminous?
A candle is a luminous object because it emits to light by itself
What two flames flickers non-luminous or luminous?
A luminous flame flickers while a non-luminous flame remains steady.
