Question

4 If a burning candle is covered with a glass inverted on top of it. What happens?

Answer 1

When an inverted gas jar is placed over a burning candle, the oxygen supply is cut off.

• Putting the jar above the candle prevents oxygen from entering the jar.
• Only the oxygen in the jar can be used in the reaction.
• Oxygen is the main source to undergo the complete Combustion.
• All the oxygen gets converted into carbon dioxide. Carbon dioxide does not support burning. As a result, the candle burns out after a while.
