Why a Bunsen burner has wide heavy base?
To keep it from tipping over while in use.
How do you set up a Bunsen burner?
First you need a tripod,gauze mat and a container whatever your gonna heat. Connect the hose to the gas. While lighting the Bunsen burner slowly turn the gas on. Make sure that the hole is close when you light it.
What were the benefits of the Bunsen Burner?
to heat things up, to hold test tubes while the get heated (mostly to heat things up)
What is Bunsen burner and how it is used?
When the University of Heidelberg hired Robert Bunsen in 1852, the authorities promised to build him a new laboratory building. Heidelberg had just begun to install coal-gas street lighting, so the new laboratory building was also supplied with illuminating gas. Illumination was one thing; a source of heat for chemical operations something quite different. Previous laboratory lamps left much to be desired regarding economy and simplicity, as well as the quality of the flame; for a burner lamp, it was desirable to maximize the temperature and minimize the luminosity. While his building was still under construction late in 1854, Bunsen suggested certain design principles to the university's talented mechanic, Peter Desaga, and asked him to construct a prototype. The Bunsen/Desaga design succeeded in generating a hot, sootless, non-luminous flame by mixing the gas with air in a controlled fashion before combustion. Desaga created slits for air at the bottom of the cylindrical burner, the flame igniting at the top. By the time the building opened early in 1855, Desaga had made fifty of the burners for Bunsen's students. Bunsen published a description two years later, and many of his colleagues soon adopted the design. The device in use today safely burns a continuous stream of a flammable gas such as natural gas (which is principally methane) or a liquefied petroleum gas such as propane, butane, or a mixture of both. The burner has a weighted base with a connector for a gas line (hose barb) and a vertical tube (barrel) rising from it. The hose barb is connected to a gas nozzle on the lab bench with rubber tubing. Most lab benches are equipped with multiple gas nozzles connected to a central gas source, as well as vacuum, nitrogen, and steam nozzles. The gas then flows up through the base through a small hole at the bottom of the barrel and is directed upward. There are open slots in the side of the tube bottom to admit air into the stream via the Venturi effect, and the gas burns at the top of the tube once ignited by a flame or spark. The most common methods of lighting the burner are using a match or a spark lighter. The amount of air (or rather oxygen) mixed with the gas stream affects the completeness of the combustion reaction. Less air yields an incomplete and thus cooler reaction, while a gas stream well mixed with air provides oxygen in an equimolar amount and thus a complete and hotter reaction. The air flow can be controlled by opening or closing the slot openings at the base of the barrel, similar in function to a car's carburetor. If 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, appearing blue as a result. If the holes are closed, the gas will only mix with ambient air at the point of combustion, that is, only after it has exited the tube at the top. This reduced mixing produces an incomplete reaction, producing a cooler but brighter yellow which is often called the "safety flame"or "luminous flame". The yellow flame is luminous due to small soot particles in the flame which are heated to incandescence. The yellow flame is considered "dirty" because it leaves a layer of carbon on whatever it is heating. When the burner is regulated to produce a hot, blue flame it can be nearly invisible against some backgrounds. Increasing the amount of fuel gas flow through the tube by opening the needle valve will of course increase the size of the flame. However, unless the airflow is adjusted as well, the flame temperature will decrease because an increased amount of gas is now mixed with the same amount of air, starving the flame of oxygen. The blue flame in a Bunsen burner is hotter than the red flame. Many lab accidents are related to burn injuries or exposed flames, and as a result new students are trained carefully in the use of a Bunsen burner. In general, the user should make sure that hair and clothing are secure, and unlikely to fall into the flame. In addition, flammable chemicals should be kept away from the Bunsen burner, and someone should remain by the burner at all times to supervise it. The flexible rubber hose connecting the Bunsen burner to the gas nozzle on the lab bench should also be secure, with no evidnce of leaking, and people should be cautious about touching things which have been exposed to the often considerable heat of a Bunsen burner, especially glass objects.
What While conducting an experiment using the scientific method scientist should?
observe and record data.
Why do you use the blue flame while using a Bunsen burner?
hottest part of flame
How can you minimise risks when using a Bunsen burner?
You can place a wire gauze on top of it and keep a safe distance away form the bunsen burner. Try not to perform anyexperiments while sitting down- it is safer while standing.
Different kinds of burner?
Three types of laboratory burners are the Tirrill Burner, Bunsen Burner, and the Meker Burner. The Tirrill and Meker Burner have air and gas adjustments while the Bunsen Burner has only an air adjustment. Hope that helps.
The function of a base in the Bunsen burner?
The base of a Bunsen burner allows it to remain stable while standing.
What items is used to distribute heat from a Bunsen burner when heating the bottom of a crucible?
A crucible is placed in a pipestem triangle placed on an iron ring while being heated. This supports the crucible while allowing the bottom of the crucible to be directly exposed to the flame of the Bunsen burner. There is no item that is used to distribute heat from a Bunsen burner when heating the bottom of a crucible. The bottom of the crucible is intended to be exposed to the direct flame of the Bunsen burner.
Why a Bunsen burner has wide heavy base?
To keep it from tipping over while in use.
What happens when you put salt in water while a Bunsen burner is heating it up?
The water will evaporate
What is a Tripod and a gauze mat?
In Science, a tripod is a piece of equipment, used to hold a beaker or container. The gauze mat is what is placed ontop of a tripod to hold said beaker/container. These two pieces of equipment are usually accompanied by a bunsen burner.
What happens to a piece of porcelain when heated on a Bunsen burner?
Nothing! but if you keep it in for a while, the flame turns orange
How do you set up a Bunsen burner?
First you need a tripod,gauze mat and a container whatever your gonna heat. Connect the hose to the gas. While lighting the Bunsen burner slowly turn the gas on. Make sure that the hole is close when you light it.
Can you be hurt by a gauze mat?
a gauze mat is a wire mat which can be used to hold things while they are being burnt in the lab
What should you do if the flame of the laboratory burner goes out while you are using it?
U should replace the fuel and remove ur experiment
