Turning off the Bunsen burner at the gas tap puts out the fire because the gas is a switch that lets the amount of gas that you want to burn. And if you turn it off then it would let no gas through and there for would not let the Bunsen burner light up.
Hope this helps
If your shirt catches fire while leaning over a Bunsen burner, it is likely because the fabric is flammable and has come into contact with the flame. To prevent this, it is important to always tie back loose clothing when working near an open flame and be mindful of potential fire hazards.
It is better to use a blue flame on a Bunsen burner because it indicates complete combustion of the gas, resulting in a hotter and more efficient flame for heating or sterilizing purposes. A blue flame also produces less soot and smoke compared to a yellow or orange flame.
A Bunsen burner helps us by providing a controlled and adjustable flame for heating, sterilizing, and carrying out chemical reactions in a laboratory setting. It allows for precise temperature regulation and efficient heating of substances.
A Bunsen burner typically consists of a base, gas inlet tube, air control collar, barrel, and burner tip. The base is used to stabilize the burner, the gas inlet tube connects to the gas source, the air control collar adjusts the air flow, the barrel houses the flame, and the burner tip is where the gas mixes with air and ignites.
A small fire. Remember, people didn't need Bunsen burners until they needed a constant source of heat. By the time that science required such a thing, manufacturing had advanced to the point where Bunsen burners were easy to create.
Bunsen burners are preferred over candles or fires because the Bunsen burner produces a much higher temperature (noted by the blue flame) and it is much easier to contain/control a Bunsen Burner flame.
Turning off the Bunsen burner after boiling a leaf is important to prevent the leaf from burning or catching fire. Boiling a leaf is typically done to soften it for further study or observation, and leaving the Bunsen burner on could result in overheating the leaf and damaging it.
it is the fire
Yes they are used for heating small amounts of liquids!
because the fire will burn up the shelf.
Because it is a much more reliable source of heat/fire: You can control the 'strength' of it too, by using the cap which has a hole in it at the bottom - by turning it, you can control the amount of oxygen being fed into the flame.
Turning off a Bunsen burner when used with alcohol is necessary to prevent any alcohol left in the burner from igniting and causing a fire hazard. Alcohol can continue to burn even when the flame is extinguished, so it is important to always ensure the burner is completely turned off.
Heat/Fire lol
it might set fire
A lit Bunsen burner should never be near alcohol because alcohol is flammable and highly combustible. If the alcohol were to accidentally catch fire from the Bunsen burner, it could cause a dangerous and uncontrollable fire. It is important to always follow proper safety protocols and keep flammable substances away from open flames.
Because more oxygen is needed for fuel for fire.
the gas from the Bunsen burner will cause the existing flame to flare and burn the entire piece of paper and your fingers - and the lab. it's difficult to blow out the burning paper.
