A Bunsen Burner has an air hole at the base of the burner tube.
When closed', the flame is bright yellow and slick. The flame is 'cool'. The yellow colur are white hot particles of carbon.
When 'open,' the flame is pale blue and roaring. The flame is 'hot'. The pale blue colour is carbon dioxide being formed from atmospheric oxygen.

What kind of flame do you get from a good Bunsen burner?
Im Only 14 But I Hope This Helps A Good Bunsen Burner is used in laboratories to heat things. A Bunsen burner can produce 3 different types of flames: The "coolest" flame is a yellow / orange color. It is approximately 300°C. It is never used to heat anything, only to show that the Bunsen burner is on. It is called the safety flame, The medium flame, also called the blue flame or the invisible flame is difficult to see in a well-lit room. It is the most commonly used flame. It is approximately 500°C, The hottest flame is called the roaring blue flame. It is characterized by a light blue triangle in the middle and it is the only flame of the 3 which makes a noise. It is approximately 700°C. The Flame Changes Colour Depending On The Air Hole Thingy On The Bunsen Burner.
Why should a lit Bunsen burner never be left unattended?
A lit Bunsen burner should never be left unattended because it poses a fire hazard. The open flame can easily ignite nearby flammable materials if left unsupervised. Additionally, leaving a Bunsen burner unattended can also lead to accidental spills or leaks of gas, which can result in dangerous situations. It is crucial to always monitor a lit Bunsen burner to ensure safe laboratory practices.
How do you clean a Bunsen burner?
Wait till it cools off, then wipe the outside with a damp cloth. Unless you got chemicals on it, though, you usually don't need to--the flame is above the barrel, and the fuel burns off when you turn off the gas. You could also do the next answer too... - - - - - Put it in the dishwasher.
Heated test tube using burner with closed air holes?
Heated test tube with a bunsen burner with closed air holes would result to the test tube having some kind of black material at the bottom, it looks like a burnt coal that stick to the bottom of the test tube. This happens because the flame is not a good flame.
What is meant by the term flame retention?
Flame retention refers to the ability of a burner to maintain and stabilize a continuous flame during combustion. Good flame retention is important for efficient burning of fuel and reducing emissions in combustion systems.

What does a gentle flame on a Bunsen burner do?
A blue flame is neither too hot or too cold as somebody else has said. But the gentle blue flame is good for heating something up with a temperature that is between the yellow safety flame and the roaring blue flame.
What is the hottest part of the roaring Bunsen burner flame?
The blue part of the flame, the cone in the middle is the hottest, the flame cools as it gets further away from the burning centre, this is similar to the sun where the outer surface of the sun is significantly cooler compared to the inside.
When do we need to use the blue flame on a Bunsen burner?
Good question, well the answer to that is when you're feeling all rambo style and being an idiot you stick your hand in..
Why when heating most organic volatile liquid's is it a good idea to use steam and not a Bunsen burner?
Using steam for heating organic volatile liquids can provide a more controlled and gradual heating rate, reducing the risk of overheating and causing explosions or fires. On the other hand, a Bunsen burner's open flame can quickly raise the temperature of the liquid, increasing the chances of ignition and posing a safety hazard. Additionally, steam heating can prevent direct contact between the liquid and the heat source, minimizing the possibility of thermal decomposition or degradation of the organic compound.
Why is it important that you should tie your hair back when using a Bunsen burner?
It is important to pull your hair back when using a Bunsen burner to prevent it from coming into contact with the open flame and igniting your hair.You are instructed to pull back your hair when using a Bunsen burner to prevent your hair from coming into contact with the open flame and catching your hair aflame.
What apparatus apart from a bunson burner is used for heating elements?
Aside from the Bunsen burner for heating elements alcohol lamp could be of good use too.

What wire is used to spread the heat from a Bunsen burner?
A nichrome wire is commonly used to spread the heat from a Bunsen burner due to its high melting point and good heat conduction properties.
What is a Bunsen burner and its parts and how is it used?
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.
Can I safely use old heating oil?
Yes, but a water trap and good filter must be installed before the old heating oil reaches the burner, or a flame-out will occur that can result in a service call, and worse, frozen water pipes and frigid rooms.
