How does adjusting the barrel on the Bunsen burner affects the flame?

The bottom of a Bunsen burner contains holes that allow air flow. When there is no air flow, the temperature of the flame will be hotter. With the holes wide open, the flame will not be as hot.

∙ 13y agoThe flame of a Bunsen burner can be changed in two ways. First, you can change fuel intake (the fuel is usually methane), and second, you can change your oxygen intake.
In general, the fuel control affects the size of your flame, while the oxygen control affects the temperature.
