When you open the air hole, more oxygen is supplied to the flame, causing it to burn brighter and hotter. Closing the air hole restricts the oxygen supply, leading to a smaller and weaker flame, or it may extinguish the flame if there is not enough oxygen to sustain it.
A Bunsen flame is hottest when the air hole is open. When the air hole is open, more oxygen can mix with the gas, resulting in a hotter and more efficient flame. Closing the air hole restricts the amount of oxygen, leading to a cooler flame.
Air hole fully open gives a 'roaring blue flame'
When the air hole is half open, the flame is called a "medium" or "moderate" flame. This means it is not burning too high or too low and is at an optimal level for cooking. Adjusting the air hole can help control the intensity of the flame.
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 flame is opened, more oxygen is introduced to the combustion process, resulting in increased fuel burn rate and heat output. This typically leads to a hotter flame temperature due to the enhanced oxygen supply supporting more vigorous combustion.
A Bunsen flame is hottest when the air hole is open. When the air hole is open, more oxygen can mix with the gas, resulting in a hotter and more efficient flame. Closing the air hole restricts the amount of oxygen, leading to a cooler flame.
With the air hole fully open, the flame will be fierce, but I doubt if it can be said to be dangerous. Simply close the air hole a little.
Air hole fully open gives a 'roaring blue flame'
To heat chemicals or substances in science lab for experiment. There is an air hole in the Bunsen burner where you can screw loose to have open air hole that is the blue flame which is hotter. When there is a close air hole then the flame would be orange in color which is not as hot compared to the blue flame.
An open flame above an air hole on a Bunsen burner is called a roaring flame. It occurs when the air hole is fully open and allows for more oxygen to mix with the gas, creating a hotter and louder flame. Adjusting the air hole can help control the flame temperature and intensity.
A hot flame is obtained (but not the hottest) with a color violet-white.
When the air hole is half open, the flame is called a "medium" or "moderate" flame. This means it is not burning too high or too low and is at an optimal level for cooking. Adjusting the air hole can help control the intensity of the flame.
No, the flame will not be steady when the air hole is half open. The air hole controls the amount of oxygen reaching the flame, so having it only half open will disrupt the flame's stability, causing it to flicker or sputter. Adjusting the air hole to the correct setting will help achieve a steady flame.
To get a roaring (blue) flame you simply turn the sleeve on the Bunsen burner's chimney to completely open the air hole under it. The new blue flame will be hard to see so close the air hole afterwards to make a visible flame.
Flame is stronger since there is no way for the gas to escape but through the top.
You think probable to a diffusion flame.
When the air hole is opened completely then the flame would turn blue indicating it is very hot. If you closed it the flame will be yellow indicating that it is not as hot (also called the safety flame). So if you half opened the hole then the flame would be hot but not as hot as the blue flame, due to the air flow mixing with the gas inside.
