Light a short candle on a flat table and allow it to burn properly. Cover with a light glass cup and leave it for some minute. What happens to the light candle covered
When a lighted candle is covered with a light glass cup, it creates a closed environment inside the cup. The flame of the candle consumes the oxygen inside the cup, causing the oxygen levels to decrease. As the oxygen supply gets depleted, the flame slowly starts to die down.
Eventually, the flame will extinguish completely because fire requires oxygen to sustain itself. The lack of oxygen inside the cup prevents the flame from receiving the necessary oxygen supply, resulting in its eventual extinguishment.
