What else can I help you with?
What influence does opening and closing the air holes of the Bunsen burner have on the amount of air mixing with the gas?
Opening the air holes increases the amount of air mixing with the gas, resulting in a hotter and more efficient flame. Closing the air holes reduces the amount of air mixing with the gas, leading to a cooler and less efficient flame. Adjusting the air holes allows for better control of the flame temperature.
What happens to the color of the flame if you open the air mixture valve wide open?
The flame itself will get bigger/hotter, and the amount of 'blue' increases. Depending on the type of burner, it may or may not increase proportionately with the total flame size.
What is the colour of the flame seen when sulphur burns in air?
The color of the flame seen when sulfur burns in air is blue.
What is the colour of the flame when sulphur burns in air?
blue
What influence does closing and opening the air holes have on the amount of air mixing with the gas?
Closing the air holes reduces the amount of air mixing with the gas, resulting in a more fuel-rich mixture. Opening the air holes allows more air to mix with the gas, creating a leaner mixture. This adjustment impacts the combustion process and can affect the efficiency and performance of the system.

What happened to the flame as you covered the air holes?
The flame will start to weaken and eventually go out as you cover the air holes. This is because the flame needs oxygen to sustain combustion, and by covering the air holes, you are restricting the flow of air needed for the flame to burn.
What flame is what you called when air holes are closed?
Safety flame
Do closing air-holes on a Bunsen burner make the flame hotter?
Because more air is able to fuel the flame's reaction; the collar at the bottom of the tube is adjusted so more air can mix with the gas before combustion, the flame will burn hotter.
What causes the luminousity of a flame?
Flame luminosity occurs because of lack of oxygen. Also, the air holes in the Bunsen burner affects the flame.
What happens to the color of the flame if you open the air mixture valve wide open?
The flame itself will get bigger/hotter, and the amount of 'blue' increases. Depending on the type of burner, it may or may not increase proportionately with the total flame size.
What happens to the flame if the air holes are open too much?
If the air holes are open too much, it can lead to an influx of oxygen that may cause the flame to burn too hot and inefficiently. This can result in increased fuel consumption, uneven heating, and even potential safety hazards. Adjusting the air holes to the correct setting helps maintain a steady and controlled flame.
What is the colour of the flame seen when sulphur burns in air?
The color of the flame seen when sulfur burns in air is blue.
What happen to the flame when the air holes are closed of the bunsen burners?
When the air holes of a Bunsen burner are closed, the flame will turn yellow and become sooty due to incomplete combustion. This is because the lack of oxygen restricts the amount of air reaching the flame, leading to inefficient burning of the fuel gas.
Why does opening the air hole in a Bunsen burner make the flame hotter?
Opening the air hole in a Bunsen burner allows more air to mix with the gas before combustion, creating a more efficient and hotter flame. This increased supply of oxygen enhances the combustion process, resulting in a higher temperature flame.
What is the colour of the flame when sulphur burns in air?
blue
How the flame produced when the air holes were closed. if the the flame was luminous what made it so?
When air holes are closed, oxygen supply decreases, leading to incomplete combustion and the production of soot particles. These soot particles can get heated up to incandescence and emit visible light, creating a luminous flame. The presence of carbon in the soot is what causes the flame to appear luminous.
