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
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.
If oxygen's excluded, any. As fire needs oxygen to burn, if it lacks this, it won't burn.
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.
Burning a candle at both ends means using up its fuel source twice as fast, causing it to burn out quickly and not last as long as if it were burned from one end. It can also create a larger flame, more smoke, and potentially lead to the candle dripping wax.
Put the candle on a technical balance.
It would stop burning if there was no oxygen.

A burning candle - until it ran out of air.
Could you rephrase this? It is hard to tell exactly what the question is.
Yes, candle burning is a reversible change because it can be undone by extinguishing the flame. When the flame is removed, the wax solidifies again, demonstrating that the process of burning is reversible by cooling down the wax.

It dies.
so if it falls over the water will put out the fire instead of burning down you house. and it looks cool
