Answer 1

Answer:

4 ans :- Oxygen is the fuel for wax and makes the wick burn. When the candle is closed with the glass jar the oxygen supply is stopped. Initially, the candle burns by making use of the oxygen within the glass and slowly when there is no oxygen the flame goes off.

5 ans :- A fire cannot burn without oxygen. ... It should be noted that in the presence of carbon, nitrogen and oxygen, stars heavier than the Sun may burn hydrogen to helium by using the C, N and O as catalysts. Even in these stars, however, an absence of oxygen does not prevent nuclear burning.
