A candle goes of after sometime when it is covered with a jar because for combustion to occur, oxygen is needed. The act of keeping of jar cuts the supply of oxygen and the flame extinguishes. Hope it helps u. Because air is everywhere and it contains gases like carbon dioxide,nitrogen,oxygen etc

Because the oxygen supply gets cut off
Explanation:
Combustion requires oxygen. That is why the innermost part of the flame is blue because it lacks oxygen supply. Thus, when you cover the burning candle by a tumbler/jar, the oxygen cannot go inside and combustion cannot take place.
