A Bunsen burner simply burns everything around it. It oxidises any impurities in the surrounding area, removing particulates such as carbon and changing them into carbon dioxide, these gasses then dissapate away from the area, sterilising the area.

What is a Bunsen burner and what is its function?
The bunsen burner is used to heat items for experiments using a controllable temperature flame and surface area at which the heat is applied to the vessel.
What are the advantages and disadvantages of each type of flame of the Bunsen burner?
It is less hotter than non luminous flame. Used for lighting only It produces soot that makes apparatus sooty
How does a automatic spark ignitor work on a gas appliance?
An automatic spark ignition (igniter) works by allowing a spark to come on at the same time the gas comes on. The spark ignition module is inside the burner area. The burner should then light.
What is safety tongs?
hi safety tongs is an object used to in science experiments. for examle, when you need to pick up a boiling beaker from the bunsen burner how do you do it?? well you use saftey tongs to not burn yourself and to pick the beaker up. its a really helpful piece of equipment!!! What is the definition of safety tongs? A type of handling tool that allows press operators to enter the die area without using their hands. A press operator manipulates the tongs to grab the part from the die area. Link to picture is just below this answer.
How often should spills of blood and other potentially infectious body fluids be cleaned up in the laboratory area?
Uhhh often? Clean every spill immediately and sterilize the possibly infected area and once after everyone leaves kind of often?

Why is the base of the Bunsen burner of large area?
Perhaps I'm wrong, but this strikes me as an easy one. Why is the base so large? So it's harder to knock over when people are moving about in the lab.It prevents the burner from falling over.
What was Robert Bunsen best remembered for?
He is best remembered for inventing the burner which still bears his name. The Bunsen burner is practical because it focuses a lot of heat in a small area, making it efficient for heating small vessels such as a test tube. Also, the heat rises straight up from the burner, meaning excess heat escapes vertically and not outward toward the person using it. So it's efficient and safe.

It is less hotter than non luminous flame. Used for lighting only It produces soot that makes apparatus sooty
Why do you use the Streak Plate Technique in microbiology?
You first inoculate your loop with bacteria and streak a few times across your plate, heat your loop on a bunsen burner to sterilize it and let the loop cool to. Bring your loop back onto where you previously streaked a few times swiping back and forth....heat loop again to sterilize and let it cool. Then the last and third time take your inoculating loop back on where you streaked last time back and forth a few time across the plate always turning your plate 90 degrees. Always remember to stay close to the bunsen burner so you are in the sterile area of the flame to prevent any unwanted contamination of your bacteria. After your media is incubated you should notice 3 streak marks and the third streak mark should be the most dilute where the bacterial colonies are separate and easily observed and can be used further, if needed.
Which safety precaution is recommended when a liquid is being heated in a test tube?
Wear goggles and a laboratory apron Hold the test tube with a test tube clamp not in your bare hand. If the liquid is nonflammable it may be heated in the flame of a Bunsen burner, otherwise a hot water bath over a hot plate may be more advisable. If heating in the flame of a Bunsen burner hold the test tube at an angle and move the tube in and out of the cool area of the flame. Alway point the opening of the test tube AWAY from yourself and others.
How could you use a piece of iron wire to find the hottest part of a Bunsen burner?
by having 4 iron wires and placing each one of them in different parts of the flame observe the wire then record results not what wire is placed at what part of the bunsen then see which one is the most red (the more red the more hot the area of the flame you have out it on for it to be a fair test you should have the bunsen on a yellow/orange flame and hover the wire with tongs at the different areas do not change to a blue flame for a different wire,this was out of common sense but i dont know if my theory is correct
Why do you heat flammable liquid such as methanol with an electric heater rather than a Bunsen burner?
Two main reasons - one is that the bunsen burner flame is actually quite small in relation to the dimensions of the bottom of the beaker. If you take something that has a small surface area in relation to the size of the flame (for example a glass rod) that can be made to soften in a bunsen burner flame much more easily. The second reason is that the beaker or flask will generally contain something that you are trying to heat up or boil. So heat energy from the flame will initially transfer through the glass into that substance and be "used up" in bringing this liquid up to its boiling point,
What is a wing top or flame spreader and how is it used?
A wing top is an accessory that can be used with a Bunsen burner to provide a broad flat fan flame, similar to that of a fishtail burner. It is often used to bend glass as it spread out the heat over a larger area, making it more uniform.See the Web Links to the left for a picture.
What happens when I hold a wet cardboard over a Bunsen burner flame vertically and horizontally?
Because the position of the cardboard is vertical it obviously displays the intensities of theheat. The bottom of the cardboard displays the hottest part of the flame where the char is firstseen. While the top area of the cardboard took time to dry up and char because is cooler in thisarea that those at the bottom.
Why some candles unscented?
Not every candle burner is interested in a scent throughout the living area.
What was Joseph Lister's discovery?
Joseph Lister is credited with the discovery of carbolic acid which is used to sterilize surgical instruments. He is considered a pioneer in the area of antiseptic surgery.
