You need to open up the air intake by screwing the barrel...usually counterclockwise.
Rotating the barrels for the access of more air (oxygen).
Twist the collar.
The blue flame of the Bunsen burner is when it is hottest. The yellow flame is the safety flame. you should always start the burner on the safety flame which is produced when the holes on its base are closed.
The yellow flame because that is the safety flame
The two types of flames a Bunsen burner can produce are a luminous, yellow flame and a "roaring" blue flame. The blue flame is much hotter than the yellow flame.
No, the blue part is the hottest. In fact, you should adjust the burner so that you only have a blue flame. A yellow/orange/red flame is indicative of incomplete combustion (generating carbon monoxide).
Rotating the barrels for the access of more air (oxygen).
The silent flame on the Bunsen burner is the yellow/orange flame.
As a safety flame, keep it on this if the burner is not in use :)
yellow flame
Twist the collar.
Yellow soot is obtained when the holes of the burner are not clean. The combustion is incomplete. The yellow soot or yellow flame is because of unburnt carbon particles.
No, a yellow flame is colder than a blue flame.
Rotating the barrel of the burner.
You adjust a rotatable thing at the bottom, normally there is a hole that will become either closed or open to change the flame.

The coolest flame on the Bunsen burner is the yellow-orange flame - approx. 300 0C.
