Why does a candle go out when a jar is put over?
A candle goes out when a jar is put over it because the jar restricts the flow of oxygen to the flame. A flame needs oxygen to burn, and when the oxygen supply is limited inside the jar, the flame will eventually suffocate and extinguish.
How long does it take for a candle to go out in a bell jar?
The time it takes for a candle to go out in a bell jar depends on the size of the jar, the amount of oxygen present, and the size of the candle. Generally, a candle will burn out more quickly in a bell jar due to limited oxygen supply, which is necessary for combustion to occur.
Why does a candle go out in a bell jar?
It doesn't get any oxygen and therefore the flame goes out
What caused the candle to go out?
Well mainly pressure against the flame WHEN YOU BLOW IT: Well when you put air pressure aginst the flame it causes it to go out PUT SOMETHING ON TOP: Well when you put somehting on top(such as a metal candle burner) it puts pressure against the flame...it aventually burns out
Why does a candle go out if you cover it?
In the combustion reaction, fuel and oxygen are combined and repaired into water and CO2. The water becomes steam in the air and it and the carbon dioxide both put out the fire together.

What happens when you put a glass jar on a candle example?
the candle will go out because oxygen helps in burning but a burning substance produces carbon dioxide but when we put a glass upon can carbon will heavier than oxygen and when oxygen will less candle will go out
What will happen if you put a lit candle under a glass jar of gas?
It will burn the gas out. Then go out.
What happens when you put a lid over a lit candle?
Fire dies out because a constant supply oxygen is needed to keep a fire burning. When then oxygen is removed, the fire burns the remaining oxygen until it is all gone. Normally when fire has a good supply of oxygen it give of Carbon dioxide. However without enough oxygen it gives Carbon monoxide as the oxygen is used up. When there is virtually no oxygen left, the fire goes out.
How does fire go out if its covered by a jar?
Fire requires oxygen to burn. No oxygen = no flame. When you put a flame in a jar it lives off the oxygen inside the jar for a while. Once you put a lid on the jar, eventually the jar will run out of oxygen and the flame will burn out.
What happens when you put a glass jar on a candle?
Putting a glass jar on a candle can create a greenhouse effect that traps heat, potentially causing the glass to crack or shatter from the heat. It can also increase the risk of a fire starting if the candle is left unattended. It is not safe to place a glass jar directly over a burning candle.

When you put a jar over a candle the inside of the jar becomes misty why is this?
because all the smoke that is being let off by the flame is trapped inside the jar causing it to go misty which will eventually turn into water vapour/ condensation. hope this helps :)
Why does fire rise upwards?
Hot gases have less density than cooler gasses and so they "float" (move upwards). What you see of fire are hot gases that are oxidizing and giving off light.Experiment:An interesting experiment is to put a short candle in a jar with a tight lid. Light the candle and put on the lid, measure the time it takes for the candle to "suffocate".DON'T burn your fingers now!Repeat the experiment but this time as soon as the lid is on tight drop the jar (preferably from over two meters) and see if the flame does not go out much quicker because the hot gasses will not "float" up in the accelerating frame of reference that is the inside of the jar.Make sure the jar does not break by having something soft (a pillow or jumble of rags in a basket) where the jar lands.
What is the relationship between the size of the jar and the time taken for the candle to go of?
I assume you are thinking about a situation where the jar is airtight.In this case, a larger jar will have more air in it, and therefore more oxygen; the candle will be able to burn longer in a larger jar. I would expect the time it burns to be roughly proportional to the volume of the jar.
Why does a candle go out when burning in a sealed jar?
A candle requires oxygen to burn, and when placed in a sealed jar, the oxygen supply is depleted, leading to the candle extinguishing. This happens because the flame consumes the available oxygen, creating a vacuum that eventually snuffs out the flame.
Why does a candle go out in a bell jar?
It doesn't get any oxygen and therefore the flame goes out
