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.


What makes candle go out?

A candle goes out when there is not enough oxygen reaching the flame to sustain combustion. This can happen if the candle is in a closed environment or if the wick gets too short. Additionally, external factors like a breeze blowing out the flame can also cause a candle to go out.


When a candle is put under a tumbler why its flame goes after some times?

When a candle is put under a tumbler, it consumes the available oxygen inside the tumbler and creates carbon dioxide. As the oxygen is depleted and the concentration of carbon dioxide increases, the flame goes out due to lack of oxygen to sustain combustion.


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.
