Do you know how to use bunson burners?

Answer 1

I think you mean Bunsen:

device for combining a flammable gas with controlled amounts of air before ignition; it produces a hotter flame than would be possible using the ambient air and gas alone. Named for Robert Bunsen, the German chemist who introduced it in 1855 (from a design by Peter Desdega or Michael Faraday), the Bunsen burner was the forerunner of the gas-stove burner and the gas furnace. The Bunsen burner consists of a metal tube on a base with a gas inlet at the lower end of the tube, which may have an adjusting valve; openings in the sides of the tube can be regulated by a collar to admit as much air as desired. The mixture of air and gas (optimally about 1 part gas to 3 parts air) is forced by gas pressure to the top of the tube, where it is ignited with a match. It burns with a pale blue flame, the primary flame, seen as a small inner cone, and a secondary, almost colourless flame, seen as a larger, outer cone, which results when the remaining gas is completely oxidized by the surrounding air.

Answer 2

Yes

Step 1 - Locate burner
Step 2 - locate gas tap
Step 3 - Connect rubber tube between burner and tap
Step 4 - Choose a suitable incendiary device. e.g. a match
Step 5 - Turn on gas tap
Step 6 - Ignite gas

And remember that with the airway at the bottom of the burner open you will get a yellow flame, with it closed you will see a blue flame. A blue flame burns hotter than a yellow flame, and the hottest part of a blue flame is the tip of the inner (more intense) flame.

Don't ask me how i remember which part of a flame is the hottest! I cant remember what day of the week it is half of the time, isn't it funny how odd little facts like that can stick in your mind!!

Answer 3

Just to clarify some of the wrong answers you are getting, with the air inlet in the closed possition you get a yellow flame. this is because there is insuficient oxygen surounding the flame to get complete combustion ( if you hold a slide over the flame for a moment you will get a carbon deposit on the surface )
As you progressively open the air inlet more oxegen is mixed with the gas prior to combustion at the top of the bunsen. The flame starts to change from a flickering yellow to a small blue cone shape. This is a much hotter flame and will leave no carbon on a slide placed in the flame because you are getting complete combustion ( no unburnt carbon ). Hope that helps!

Answer 4

An efficient bunsen burner (a Meker burner) can achieve a temperature of 1200 centigrade but usually the temperature of a 'school' bunsen is about 1000 centigrade.

Answer 5

Bunson burners are used in chemical labatories to heat the compounds so that they preoduce a reaction.

Answer 6

It's Bunsen not bunson. Yes I know how to use one, are you asking for me to tell you how to use one?

1. Connect Bunsen to gas tap.
2. Check that the air inlet is closed
3. Turn gas tap on
4. Light Bunsen
5. Adjust gas flow to appropriate flame level
6. Open inlet to turn flame blue
7> Try not to burn youself (or anything else)
8. Turn off at the gas tap before leaving the room.

Answer 7

Yes
Step 1: Turn on gas supply , ensuring air flow valve [hole on the stem of burner] is open .

Step 2 : Ignite the gas.

Step3: close air flow valve , to ensure a strong blue flame.

Answer 8

Yep. Attach to gas tap, close air hole, switch on gas and light, preferably with splint but match would do. If you want to heat something quickly close the air hole. The flame will turn blue (roaring flame) and become considerably hotter.

Answer 9

yes!! doesnt everyone?

with the air intake closed you have a yellow flame, that is not very hot,, as you open up the intake the flame turns blue and gets much hotter, with it full open the hotest part is the top of the inner blue cone

Answer 10

I think, probably, you intended to ask the question: How to use a Bunsen Burner?

It should be immaterial to you if we know or not to use the burner.
