Oxygen is needed for burning. If there is no oxygen flame dies.
depends on the direction you turn the collar. You may cause the air holes to enlarge and let more air into the barrel of the burner. Or you could be making the holes smaller and actually cut off the air supply making the burner less effective, burning at a lower temp because of the lack of oxygen.
the burner stops burning
A combustion reaction stops when its supply of oxygen is cut off. Combustion requires oxygen to sustain the chemical process of burning, where a fuel reacts with oxygen to produce heat and light. Without oxygen, the reaction cannot continue, leading to the extinguishing of the flame. This principle is often utilized in fire suppression methods.
The type of reaction most likely to stop when you cut off its supply of oxygen is a combustion reaction. Combustion requires oxygen to sustain the exothermic reaction between a fuel and oxidizer, producing heat and light. Without oxygen, the reaction cannot continue, leading to the extinguishing of the flame or burning process.
The candle burning is a chemical process.
When a wide-mouthed jar covers a candle, it creates a lack of oxygen inside the jar. The flame needs oxygen to burn, so when the oxygen supply is cut off, the flame extinguishes due to the lack of a crucial element for combustion.
To cauterize a cut flower, immerse the fresh cut stem end in boiling water for ten seconds, or hold it over a candle flame until the ends are sealed.
The "air-hole" of a bunsen burner allows some of the flame to escape so that the heating flame does not become too hot. A flame that is too hot can damage laboratory equipment. When the air hole is closed it is a yellow sooty flame like the fires we have at home.
simply cover a burning candle with a glass to cut off the air, then the candle will burn out
Yes, trimming the wick of a candle to about 1/4 inch before each use helps promote an even burn and prevent soot buildup. Always trim the wick when the candle is cool and not burning.
As we know that for an object or substance to burn, its by means of carbon. Fire is very complex and needs oxygen for it to burn so by putting a beaker over a candle you are actually cutting the consumption of oxygen by fire, which will stop the fire from burning. THAT ANSWER IS FALSE. Because the candle is under a beaker and most beakers have lips the beaker is not fully cut off from oxygen so there is still oxygen. The candle does go out because of the carbon dioxide that is in the beaker
To safely put out a sterno flame, carefully cover it with a metal lid or snuffer to cut off the oxygen supply. Do not blow on the flame or attempt to extinguish it with water. Wait for the flame to completely go out before moving the sterno container.
depends on the direction you turn the collar. You may cause the air holes to enlarge and let more air into the barrel of the burner. Or you could be making the holes smaller and actually cut off the air supply making the burner less effective, burning at a lower temp because of the lack of oxygen.

To put out a Bunsen burner, simply close the air vent to cut off the oxygen supply first, then turn off the gas supply using the valve on the burner. Never use water to extinguish a Bunsen burner as this can spread the flame.
To cut a candle in half, you can use a sharp knife or a sturdy utility knife. It's best to warm the candle slightly to soften the wax, which makes cutting easier. Alternatively, you can also use a saw designed for cutting soft materials if the candle is particularly thick. Always take care to cut slowly and steadily for a clean cut.
The Bunsen burner would display complete combustion by producing a "roaring" blue flame and it would display incomplete combustion when you close the air valve complete to cut off the oxygen gas supply, thus creating a yellow flame due to the burning of carbon particles (soot).
