What type of flame when air hole is closed?
When the air hole is closed, a yellow, sooty flame is produced due to incomplete combustion. This type of flame may release more harmful pollutants such as carbon monoxide and particulate matter. It is important to ensure proper ventilation to maintain a clean and safe burning environment.
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.
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.
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.
What are the two colors of a Bunsen burner flame?
The two colours are yellow - when the air-hole is open, and blue - when the air-hole is closed.
Why is it that when the air hole is closed the flame became yellow?
The flame becomes yellow because the presence of carbon particles formed by incomplete combustion due to a lack of oxygen caused by the closed air valve.
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.
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.
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'
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.
What are the difference between the flame in a Bunsen burner when the air hole closed and open?
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.
What is the sound of a Bunsen burner when the air hole is closed?
The Answer:When the air hole is closed it is a yellow sooty flame like the fires we have at home.When the air hole is open it is purple on the outside and blue on the inside.This information is correct and safe to use.Thank You.
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.

In luminous flame the flame is produce when the air hole is open or close?
A bunsen burner (as used in a science lab or science classroom) will burn quietly, and a flickery yellow (like a wax candle) if the air hole is closed, or closed too much. If the air holes is opened, the flame will turn bluish and become noisy and hotter as more air mixes with the gas.
