What is turned to used to change the type of flame a Bunsen burner produces?

You would turn the collar on a Bunsen Burner so that the holes are exposing the flame to more oxygen to produce a blue flame. Close the holes by turning the collar to turn it back to the yellow (dirty) flame.

Why the Bunsen burner turned off when the alcohol was place in the water bath?
Boiling alcohol is a fire hazard. It contains flammable components and could result in explosions if direct heat is added. therefore, the Bunsen burner was turned off for safety purposes.
How is the amount of gas and oxygen controlled in a Bunsen burner?
the gas cannot be controlled however the oxygen can. Gas is passed through and the valve can be turned to allow more or less oxygen in, the more exposed the gas is to oxygen, the more intense the flame.
What will be the result If the gas regulator is turned clockwise while burner is still unlighted?
gas will be released
When lpg comes out from the cylinder turns to liquid to gas.is this a chemical change?
no it is not a chemical change but physical change as it can be turned back to gas by some physical or chemical process.
What is makes the flame luminous?
How: by opening up the air hole on a Bunsen burner after it is turned on.........What: Some atoms or molecules are not luminous when hot. They emit light outside the spectrum we can see, like CO2 emits infrared. Others only emit a faint color in the flame.The non-luminous is made when there is a complete combustion or complete burning process. It happens when there is more than the enough oxygen in the surroundings or in the place where the process will happen.

Is lighting a Bunsen burner a chemical reaction?
Yes, because a gas is burned - an oxydation reaction. This chemical reaction produces heat as well as carbon dioxide and water vapor as products from methane and oxygen gas. The heat also excites the electrons in the gases it produces, causing them to gain energy and rapidly emit this energy in the form of photons predominately with a wavelength of approximately 475 nm, which we perceive as blue light. The reaction can be described by the following equation: CH4 (g) + 2 O2 (g) => CO2 (g) + 2 H2O (g)
What equipment is used with a Bunsen burner?
The is an 'Air hole' at the bottom of the burner. This air hole has a slip collar , which can be twisted/turned/rotated in order to control the air flow. When the collar is turned such that the air hole is closed, then you have a 'slack' yellow flame. When the air hole is fully open , you have a 'roaring' pale blue flame. The temparture is controlled by the air hole too!!! . With the yellow flame is at its coolest, and with pale blue flame is at its hottest. However, you need a special heat resistant thermometer to insert in to the flame to read the actual temperature.

What happens if the air balloon burner was turned off?
The balloon will crash. The burner keeps it up.
What is the function of the collar of a Bunsen burner?
The collar regulates the amount of air which mixes with the fuel gas before it is burned. If the hole in the collar is not lined up with the hole in the bunsen stem, the fuel does most of its mixing with air at the top of the burner. This makes burning inefficient and the flame is cool. When the two holes line up, air is pre-mixed with the fuel, burning is much more efficient and the flame is as hot as possible.the collar of a bunsen burner is the part which doesnt get hot and you can twist it to close or open the air hole.Turning the collar opens and closes the air-hole which allows a controlled amount of oxygen to mix with the gas. The amount of air mixed in determines the colour and heat of the flame.The collar controls the amount of air and thus oxygen that can reach the methane gas inside the burner. With the hole closed there is no additional oxygen to mix with the methane and so we have a yellow flame. Opening the hole allows oxygen to mix with the methane so it burns at a higher temperature and with a blue flame.The collar on the Bunsen burner is to allocate as much oxygen as desired from the atmosphere into the Bunsen burner. The more oxygen in the Bunsen burner, the bluer or clearer the flame is. It is much hotter when in the blue flame.
What are the 5 rules that you should follow when using a Bunsen burner?
1. turn the gas on after you have lit the match. 2. make sure the tube is plugged in propperly. 3. make sure the yellow flame is on to start woth before turned to the blue. and that is all i can remember. good luck
Why is copper wire turned into grayish black when it heated on a Bunsen burner?
The black which forms on the copper is most likely carbon, produced from in complete combustion. This incomplete combustion occurs when not enough oxygen is present for all the fuel to combust. If you are using a Bunsen burner you are most likely using methane as a fuel, incomplete reaction can result in: CH4(g) + O2(g) ---> C(s) + 2H2O(g)
What would happen if you turned on the gas and let it run for a while before lighting a match to light a Bunsen burner?
Depending on what gas it is, it could be heavier than air, which would mean it could "pool" around in the room and if ignited could explode or cause a huge fireball thereby killing or injuring others. Dont do it.
What will be the result If the gas regulator is turned clockwise while burner is still unlighted?
gas will be released
Should you remove your hand from the stove burner when it is turned on?
Unless you want to suffer a severe burn, yes.
What happens to the air particles inside a hot air balloon when the burner is turned off?
they slow down
