Key Stage 3
Meaning
A picture of Bunsen Burner with a yellow flame.
A Bunsen Burner is a piece of equipment used for heating.
About Bunsen Burners
- Bunsen Burners use a flammable gas which burns to produce a flame.
- A Bunsen Burner has a valve at the bottom to allow in air. This valve can be turned to allow more or less air for combustion.
- If the valve on a Bunsen Burner is open it lets a lot of oxygen in so the flame may appear blue or may be difficult to see. This is a roaring flame at a high temperature.
- If the valve on a Bunsen Burner is closed less oxygen gets in, so the flame may appear yellow. This 'safety flame' is at a lower temperature. It is safer because it can be more easily seen and is a lower temperature.

- If the valve on a Bunsen Burner is open it lets a lot of oxygen in so the flame may appear blue or may be difficult to see. This is a roaring flame at a high temperature.
- If the valve on a Bunsen Burner is closed less oxygen gets in so there is incomplete combustion, so the flame may appear yellow due to glowing particles of soot. This 'safety flame' is at a lower temperature. It is safer because it can be more easily seen and is a lower temperature.
