A burning candle goes off when covered by a glass cup because it uses up the available oxygen in the cup, creating a sealed environment with no oxygen for the flame to continue burning. This causes the flame to extinguish due to the lack of oxygen needed for combustion.

Why does a candle extinguish itself after being covered with a glass?

The burning flame on a candle needs three things to continue burning: 1) fuel, which it gets from the wick 2) heat, which comes from lighting the candle 3) oxygen Without any one or more of these three things, the candle will no longer continue to burn. In the case where a candle is covered with a glass, the candle quickly uses up the oxygen inside the glass. once all of the oxygen is gone, the flame will burn out.


What happens to burning candle if there is no oxygen?

If there is no oxygen, a burning candle will not be able to sustain the combustion process since oxygen is needed for the flame to continue burning. The candle will eventually go out in the absence of oxygen.


A candle is covered with a flask and the flame goes out why?

When the candle flame is covered with a flask, it creates a closed system where the oxygen supply is limited. The flame requires oxygen to sustain combustion, so when the available oxygen is used up, the flame goes out. The process is known as oxygen depletion, and it happens when the flammable material (wax) fails to receive sufficient oxygen to continue burning.


Why does the candle flame goes out when placing a glass over it?

When a glass is placed over a candle flame, it acts as a barrier by cutting off the oxygen supply needed for combustion. Without oxygen, the candle cannot sustain the chemical reaction that produces the flame, causing it to go out.


Why did the candle stop burning after some time?

You do not give us the conditions when the candle stops burning, but a guess would be that the candle is in a closed container. When the candle has used up the oxygen inside the closed container, it can no longer burn, and goes out.

How can show that air support burning?

If you put an enclosed container over a candle, after a few minutes or seconds, the flame will go out. This is because when the candle burns, it releases carbon. The air around the candle contains oxygen. The carbon and oxygen combine forming carbon dioxide. When there is no more oxygen to combine with, the flame goes out.

Why does a lighted candle get extinguished when covered?

A lighted candle gets extinguished when covered because it is deprived of oxygen, which is necessary for combustion. The flame consumes the available oxygen in the enclosed space, and as the oxygen levels drop, the flame eventually can no longer sustain itself and goes out. Additionally, the buildup of carbon dioxide from the burning wick can also contribute to extinguishing the flame.

Why a candle gets extinguish when a glass is put over it?

When a glass is placed over a candle, the candle flame burns up the available oxygen inside the glass. As the oxygen is used up, the flame is starved of oxygen and eventually goes out. This demonstrates the concept of oxygen depletion leading to extinguishing of the flame.

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

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."
