When the air hole is closed, the flame will be yellow and sooty, and will produce incomplete combustion. When the air hole is open, the flame will be blue and more efficient, as it allows for complete combustion of the fuel. The open air hole allows more air to mix with the fuel gas, resulting in a hotter and cleaner flame.
When the air hole of a Bunsen burner is closed, the flame temperature can reach up to around 1,400°C (2,550°F). This is because the closed air hole restricts air from entering the burner, leading to incomplete combustion and a hotter, more sooty flame.
The name is a "safety flame". This is when the air hole on the Bunsen burner is closed, resulting in a flame with a yellow, sooty appearance. It is used for low-temperature heating applications.
Yes, the flame of a Bunsen burner with a closed air hole can still be used for heating, but it will produce a cooler, more yellow flame compared to a Bunsen burner with an open air hole. Adjusting the air hole allows for control of the flame temperature.
Closing the airhole when lighting the Bunsen burner helps create a fuel-rich environment, allowing for easier ignition. As the flame stabilizes, the airhole can then be adjusted to control the type of flame produced.
If the air hole of a Bunsen burner is closed, the flame will burn yellow with a lower temperature and produce less heat compared to when the air hole is open. The amount of heat produced would be reduced as the combustion is incomplete due to the lack of sufficient oxygen.
its a orange colour when closed and a blue colour when is open
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.

it's to prevent a strike-back
When the air valve in closed a yellow luminous flame is observed due to carbon particles from in incomplete combustion.
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.
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.
It is less hot
