if you light a candle and put it an open jar then close the top on it, wont the candles light go out?
Assuming that the jar is air tight, the flame will go out once the oxygen in the jar is used up.
thank you
Yes, if you light a candle and then put it in an open jar and close the top, the candle's flame will eventually go out. This is because the flame requires oxygen to sustain combustion. When you close the jar, the oxygen inside gets depleted as the flame consumes it. As a result, the flame becomes starved of oxygen and eventually extinguishes.
To understand why this happens, we can observe the process of combustion. When a candle burns, the heat from the flame vaporizes the wax near the wick. The vaporized wax then reacts with the oxygen in the air, producing heat, light, carbon dioxide, and water vapor. This process is known as oxidation or combustion.
When you close the jar, the initial amount of oxygen inside becomes limited. As the candle continues to burn, it consumes the available oxygen and produces carbon dioxide and water vapor. Without a fresh supply of oxygen from the outside, the oxygen inside the jar gets used up, leading to an imbalance between the consumed oxygen and the emitted gases. Eventually, the lack of oxygen causes the flame to extinguish.
In summary, closing the top of an open jar containing a lit candle will deprive the flame of oxygen, leading to its eventual extinguishment.
