because of the gravity of the sun
Down inside just below the air hole, at the gas nozzle inlet.
This is when the gas is burning at the nozzle at the base of the chimney, rather than at the top. Switch off the gas supply and start again.
The bunsen burner is very hot and you may burn yourself. Wait for it to cool down and then light it again
Provided there is an external energy source to initiate the reaction. The hydrogen coming from your Bunsen Burner did not form a vapour stream when the (hydrogen) gas was not lit. [Back when piped gas was hydrogen].
Boric Acid! When boron is heated, electrons absorb a certain amount of heat energy that causes them to jump to higher energy levels. After While, these electrons lose their energy and fall back down to their original levels, and as they do so, they emit energy in the form of light. Because the energy absorbed by electrons is different per element, each element will give a different color. Boron gives off a green color.
If the chimney is hot, it indicates that combustion is occurring inside it, not above it. If the combustion continues toward the source, it will explode, and you'll have a bad day.
That's normal. It will pull more amperage when first turned on.
strike back occurs when the air hole is opened to big or fully opened hence too much air enters and burns causing a strike back and the collar would be the hottest part of the burner during strike back
it's to prevent a strike-back
The bunsen burner is very hot and you may burn yourself. Wait for it to cool down and then light it again
It occurs when you did not fully close the air-hole on lighting up your Bunsen burner. Flames are observed to be green and it also produces a soot. Therefore we should immediately turn off the gas supply as the unburnt gas would fill the air, making the room flammable.
When strike back occurs, the first thing that one must do is backup to avoid getting burned or seriously injured. After it subsides, the person should close the burner and switch off the gas cock.
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.
how will you prevent a burner from striking back
You have to turn off the gas tap immediately.
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.
Striking back of a burner means that the burner's air hole is not open all the way. This causes an air shortage that needs to reach the gas. This results in too much air buildup through it, which causes the flame to burst out of the air hole.
stand up so the Bunsen Burner does not fall over tie hair back use a safety mat turn of after use
You should tie your back if you have long hair, make sure that the bunsen burner is standing up nice and sturdy and turn it off after using.
