The dominant color of a nonluminous flame on a Bunsen burner is blue. Whereas, the dominant color of a luminous flame on a Bunsen burner is orange.
because we use methane which burns in a blue flame.
Blue is dominant color in it .
The yellow color is from the incandescence of not burned soot particles.
when the flame comes big the color of the flame is orange but, when the flame comes small the color of the flame is blue
You reduce the supply of fuel. A "yellow" flame is a lot cooler than a "blue" flame. As it pertains to Chemistry, the dominant color for a nonluminous flame (yellow) is blue.
What colour the flame is has totally got to do with how much oxygen is allowed into the Bunsen, the flame can be anywhere between a bight orange to blue, all the way to being almost unnoticeable. This is what make them dangerous if unattended as you wont know there burning until you are. Low air easily visible flame, High air flow, and it becomes very difficult to see.
A hot flame is obtained (but not the hottest) with a color violet-white.
Blue/Turqouise
no, the blue flame is hottest
the colour of the roaring flame is blue
The yellow color is from the incandescence of not burned soot particles.
the orange flame (when the oxygen wholes are closed it makes an orange flame) because when it is on the blue flame (when the oxygen wholes are open) it is very hard to see and almost invisible
TRUE
when the flame comes big the color of the flame is orange but, when the flame comes small the color of the flame is blue
When the hole of a Bunsen burner is half closed (or half open) the flame is mostly blue-violet in color throughout, with no orange/yellow apparent as it would be with the hole fully closed. When the hole is fully open, the flame divides into a pale voilet color outer part with a cone of intense blue color within.
A properly adjusted flame on a bunsen burner would have a flame that is blue. It would also appear that there is a lighter blue flame in the center, usually referred to as an inner blue cone, the hottest part of the flame.
To heat chemicals or substances in science lab for experiment. There is an air hole in the Bunsen burner where you can screw loose to have open air hole that is the blue flame which is hotter. When there is a close air hole then the flame would be orange in color which is not as hot compared to the blue flame.

Yellow to orange at low temperatures (300-400 0C) and blue at high temperatures (500-700 0C).
