Why do candles go out when we put glass jars over them?

Answer 1

Oh, dude, it's like, science and stuff. So, when you put a glass jar over a candle, it messes with the oxygen flow that the flame needs to keep burning. It's like trying to breathe with a plastic bag over your head - not a good idea if you want to stay alive, you know? So yeah, candles need oxygen to burn, and glass jars are like, "Nope, not today, candle."

Answer 2

When a glass jar is placed over a candle, the flame consumes the available oxygen inside the jar and creates carbon dioxide. As the oxygen is depleted, the flame is deprived of the necessary oxygen to sustain combustion, causing it to go out. Additionally, the glass jar can trap heat, causing the air inside to warm up and expand, which can also contribute to extinguishing the flame.

Answer 3

Well, darling, when you put a glass jar over a candle, you're basically suffocating it. The flame needs oxygen to keep burning, and when you trap it in a glass jar, it runs out of air and fizzles out like a bad date. So, next time you want to play with fire, maybe give the candle some room to breathe.

Answer 4

The concentration of oxygen in the air in the beaker becomes insufficient for the flame to carry on burning, or the carbon dioxide produced is trapped in the beaker, and the increased concentration causes the flame to be extinguished.

Answer 5

When a glass jar is placed over a candle, the jar effectively eliminates the supply of air (oxygen) to the flame. Once all the oxygen in the jar is consumed in the combustion reaction, the flame goes out since the reaction has consumed the limiting reagent.

Answer 6

As soon as you cover a flame with a container the oxygen in the container is used by the flame. because hot gas goes up the glass ends up being filled with hot gasses that has no oxygen in it. for a candle to but it requires a constant supply of oxygen so it goes out.

Answer 7

The burning of the candle is a form of oxidation (combustion) that chemically combines the hydrocarbons in the candle with oxygen in the air, generating light and heat. Once most of the oxygen under the glass cover is depleted, the reaction stops due to lack of oxygen.

Leaving a small airspace below the glass will usually allow more oxygen to flow in, and reaction products (mainly carbon dioxide and water) to flow out.

Answer 8

A flame uses oxygen as its fuel, so once all the oxygen in the jar has been burned the flame will die.

Answer 9

A burning candle requires Oxygen to continue burning. The jar over the candle restricts the supply of oxygen and therefore the candle can not continue burning and will go out.

Answer 10

One reason that a flame may go out is because it is not getting enough oxegyn.
