A needle valve on a Bunsen burner is used to control the flow of gas, allowing for precise regulation of the flame's size and intensity. By adjusting the needle valve, the user can fine-tune the amount of gas being released, which directly impacts the flame's temperature and stability. This control is essential for achieving different heating applications in laboratory settings.

What type of energy change does a Bunsen burner use?
A Bunsen burner uses chemical energy from the combustion of a fuel, such as natural gas or propane, to produce heat energy through a flame.
What are the energy that transfers to a Bunsen burner?
A Bunsen burner typically uses natural gas or propane as a fuel source. When the gas is ignited, chemical energy is converted into heat energy, which is then transferred to the object being heated through convection and radiation.
What energy does a Bunsen burner use?
A Bunsen burner typically uses natural gas, propane, or butane as a fuel source to produce a flame for heating or sterilizing purposes. The flame is ignited by a spark or a pilot light, and the intensity of the flame can be adjusted by controlling the flow of gas and air.
What is used to provide heat in an experiment?
A Bunsen burner is commonly used to provide heat in laboratory experiments. It uses a mixture of gas and air that can be adjusted to control the temperature of the flame.
Why does the blue falme on the Bunsen burner make a hissing sound?
The hissing sound of the blue flame on a Bunsen burner is due to the rapid movement of gas molecules as they mix with air and combust. This turbulence creates vibrations and generates sound waves, resulting in the hissing noise.

parts and uses of the Bunsen burner
The Bunsen burner uses a mixture of gas and what?
air
This item is a common source of heat in a laboratory.?
A Bunsen burner is a common source of heat in a laboratory. It uses gas and air to produce a controlled flame for heating purposes.
Why is the Bunsen burner not used for heating?
the bunsun burner is used for heatin it just has other uses also
Why is it safer to evaporate alcohol using an infra red heater rather than using a Bunsen burner?
The Bunsen burner uses an ope flame, making it easier for the alcohol to ignite.
What type of energy change does a Bunsen burner use?
A Bunsen burner uses chemical energy from the combustion of a fuel, such as natural gas or propane, to produce heat energy through a flame.
What is the uses of Bunsen burners?
A Bunsen Burner, is piece of equipment particularly used in a science lab. The Bunsen Burners creates a gas flame which is used to assist in experiments. The Bunsen burner originating from 1852, given the name by Robert Bunsen.
What is a Bunsen burner and what is it's uses?
From Wikipedia (see Link to the left):A Bunsen burner is a device used in scientific laboratories for heating, sterilization, and many other uses.The device safely burns a continuous stream of a flammable gas such as natural gas (which is principally methane) or a liquified petroleum gas such as propane, butane, or a mixture of both.From ScienceByJones.com (see Link to the left):The Bunsen burner is used frequently in the laboratory as a source of heat. This burner is designed so that gaseous fuel may be mixed with the correct amount of air to yield the maximum amount of heat. In order to use this burner properly and safely, it is essential that you understand its construction and the adjustments that can be made.The three principal parts of the burner are: barrel, needle valve, and base. The quantity of gas admitted to the burner is controlled by the needle valve, while the air needed for combustion is admitted at the small opening around the bottom of the barrel. The air is controlled by turning the barrel so as to make the air holes larger or smaller.Always open the desk outlet valve fully and regulate the gas supply to the burner by the needle valve. Always extinguish your burner by turning off the desk outlet valve (and then closing the needle valve and barrel.) If there is an accident always shut off the desk outlet valve immediately.STEPS TO LIGHT BUNSEN BURNER:1. Check connections to burner and desk outlet valve.2. Close needle valve and barrel.3. Open desk outlet valve fully.4. Check for leaks with flame.5. While holding flame above barrel, open needle valve 1/2 turn.6. Adjust barrel and needle valve for blue in blue flame.Always light burner in open space on lab counter. After you have adjusted it for the flame needed move it into position. One person in lab group is always responsible for maintaining the burner and flame.Burner Procedure:1. Light the burner according to our rules. Observe the yellow flame which is produced because not enough air is admitted to give complete combustion. The yellow color is caused by small particles of unburned carbon which become incandescent.2. Now rotate the barrel until the flame is entirely blue. Two different zones should appear when the burner is correctly adjusted. Too much air should not be admitted as it may cool the flame or blow it out entirely. After having the teacher confirm a good hot, blue flame draw a diagram of the flame (use labels and descriptions). Indicate on your diagram of the flame where the hottest part of the flame is located.See the Web Links to the left for more information.Bunsen burner barrels can be rotated, either opening or closing the barrel, to adjust the flow of air or oxygen, thereby controlling the flame.
What uses of alcohol burner?
Alcohol burner, also referred to as backpacker is used to replace a Bunsen burner due to its light weight, simple style and it is handy.
What flame is used in the Bunsen burner to heat things?
The Bunsen burner uses a blue flame, which is produced when air and gas mix in the burner tube and are ignited. This blue flame is hotter than a yellow flame and is commonly used for heating in laboratories.
What is the uses of burner in laboratory?
The use of the Bunsen burner in a laboratory varies. It is mainly used for causing combustion, heating items, and sterilizing items.
What are the energy that transfers to a Bunsen burner?
A Bunsen burner typically uses natural gas or propane as a fuel source. When the gas is ignited, chemical energy is converted into heat energy, which is then transferred to the object being heated through convection and radiation.
