To get a roaring (blue) flame you simply turn the sleeve on the Bunsen burner's chimney to completely open the air hole under it. The new blue flame will be hard to see so close the air hole afterwards to make a visible flame.

FranTo create a roaring flame on a Bunsen burner, make sure the air hole is fully open and adjust the gas flow to increase the amount of gas being released. This will allow for more complete combustion and a larger, more intense flame. Additionally, positioning the collar of the burner to the "open" setting can also help achieve a roaring flame.

How can you make the height of the flame smaller on a Bunsen burner?
To make the height of the flame smaller on a Bunsen burner, you can adjust the air hole at the base of the burner. By opening the air hole slightly, less oxygen will reach the flame, leading to a smaller and more controlled flame height.
Is the hole open or closed on a Bunsen burner to make a safety flame?
The hole on a Bunsen burner should be closed to create a safety flame. This flame is smaller and more controlled, reducing the risk of accidents.
How does a yellow flame on a Bunsen burner make things black but the roaring flame doesn't?
A yellow flame produces soot when it burns incompletely, which can deposit on objects and turn them black. In contrast, a roaring blue flame burns more completely, producing less soot and therefore does not typically cause objects to become blackened.
How do you change the flame on a Bunsen burner?
To adjust the flame on a Bunsen burner, first make sure the gas is turned on. Then, slowly open the air vent to let in more oxygen, which will produce a blue, hotter flame. Conversely, closing the air vent will produce a yellow, cooler flame.
A bunsen burner is used for heating in a laboratory which safety procedure is important to follow when using a bunsen burner?
It is important to always ensure that the bunsen burner flame is turned off when not in use to prevent accidents and fires. Additionally, make sure that the bunsen burner is securely positioned on a heat-resistant surface and that there are no flammable materials nearby to prevent potential hazards.
