What is the name when the air hole is closed on a Bunsen burner?
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.
Can the the flame of closed air hole Bunsen burner can used for heating?
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.
How much amount of heat is there if the air hole of the Bunsen burner is closed?
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.
What happens when the hole on a Bunsen burner is closed?
The "air-hole" of a bunsen burner allows some of the flame to escape so that the heating flame does not become too hot. A flame that is too hot can damage laboratory equipment. When the air hole is closed it is a yellow sooty flame like the fires we have at home.
What is the name of the flame when the air hole of a Bunsen burner is open?
Air hole fully open gives a 'roaring blue flame'

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.

Does the temperature of the flame on a Bunsen burner increase when the air hole is open?
yes
Why do you need to ensure that the air hole is closed before you light the bunsen burner?
it's to prevent a strike-back
What is the flame temperature if the air hole is closed in a Bunsen burner?
The flame temperature increases significantly when the air hole is closed in a Bunsen burner because the flame becomes fuel-rich, leading to incomplete combustion. This can result in a sooty, yellow flame with a lower efficiency and higher temperature, reaching up to 1300°C (2372°F) due to the excess fuel. However, this can also create safety hazards, such as the potential for carbon monoxide production.
When air hole of the Bunsen burner is closed what is the observation?
When the air valve in closed a yellow luminous flame is observed due to carbon particles from in incomplete combustion.
When you are not using a Bunsen burner but wish to leave the flame on you should always leave the air hole closed why?
It is less hot
What covers air hole in a burner?
The function that covers the air hole in a Bunsen burner is the collar.
What is the colour of the Bunsen burner when it is halfway 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.
