What else can I help you with?
What is the color of the flame with the air vent closed?
If the air vent is closed, there may not be enough oxygen for complete combustion, resulting in a yellow or orange flame due to the presence of unburned carbon particles. It is inefficient and can produce more soot and carbon monoxide.
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
A non metal which burns with a blue flame?
Sulfur is a non-metal that can burn with a blue flame. When ignited, sulfur reacts with oxygen in the air to produce sulfur dioxide gas, which burns with a characteristic blue flame.
How do you change the flame on a Bunsen burner?
To adjust the flame on a Bunsen burner, first make sure the gas is turned on. Then, slowly open the air vent to let in more oxygen, which will produce a blue, hotter flame. Conversely, closing the air vent will produce a yellow, cooler flame.
What would be the visual signs of a flame supplied by vitiated air?
A flame supplied by vitiated air may have a yellow or orange color rather than a blue color typically seen with a clean-burning flame. It may also produce more soot and smoke, and the flame may flicker or be unstable. Additionally, there may be a noticeable odor of unburned fuel.

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.
What color flame is produced when natural gas (methane) and air are properly mixed?
When natural gas (methane) and air are properly mixed, a blue flame is produced.
When does the flame of a Bunsen burner becomes small or big?
The flame of a Bunsen burner becomes small when the air inlet is closed, leading to a fuel-rich environment. It becomes bigger when the air inlet is opened, allowing more oxygen to mix with the fuel gas and create a hotter, larger flame.
How can you tell if there is too much air mixing with the gas in a Bunsen burner?
The more air the fiercer the flame and the hotter the flame.
What science equipment used to give flame?
A Bunsen burner is commonly used in laboratories to produce a flame for heating, sterilizing, or combustion purposes. It operates by mixing gas with air and igniting the mixture to produce a controlled, focused flame.
What tool mixes gas and air to produce a hot flame?
oxy-acetylene torch
