What is the function of the needle valve in the Bunsen burner?
The needle valve controls the flow of gas into the Bunsen burner, regulating the size and intensity of the flame. By adjusting the needle valve, you can increase or decrease the amount of gas entering the burner, which in turn alters the flame's temperature and size.
Where does the air enter the Bunsen burner?
There is an opening at the bottom of the barrel above where the gas enters. There will be a valve or collar that changes the size of the opening.
What are the 5 main parts of a Bunsen burner?
Air hole, collar, barrel, base, burner tubing
How do you put a Bunsen burner out?

What controls air flow in a Bunsen-burner?
The air flow in a Bunsen burner is controlled by adjusting the collar around the base of the burner. By opening or closing the collar, you can regulate the amount of air that mixes with the gas, affecting the flame's size and temperature.
What is the function of the needle valve in the Bunsen burner?
The needle valve controls the flow of gas into the Bunsen burner, regulating the size and intensity of the flame. By adjusting the needle valve, you can increase or decrease the amount of gas entering the burner, which in turn alters the flame's temperature and size.

Function Bunsen burner?
A Bunsen burner focuses a lot of heat straight upward, instead of outward. This allows you to heat something up at close range without your hand or anything else getting too hot. Most Bunsen burners have a valve that controls gas flow and adjustable vents where you can control the amount of air that feeds the flame. Bunsen burners are a safe, practical way to apply heat in a chemistry lab.
What are the functions of the parts of a Bunsen burner?
The parts of a Bunsen burner include: the barrel, gas hose, base, collar, air hole and gas flow valve. The Bunsen burner is a small adjustable gas burner that is mainly used in scientific laboratories.
How do you control the gas entering in a Bunsen burner?
The gas flow in a Bunsen burner is typically controlled using a valve located on the gas line connected to the burner. By turning the valve, you can increase or decrease the flow of gas entering the burner, which in turn affects the size and intensity of the flame.
How does adjusting the needle valve on the Bunsen burner affect the flame?
Adjusting the needle valve on the Bunsen burner controls the amount of air mixed with the gas. Opening the valve increases air, resulting in a blue, hotter, more oxygen-rich flame. Closing the valve reduces air, creating a yellow, cooler, more fuel-rich flame.
Description of Bunsen burner?
