AIR IS NEEDED FOR BURNING

DO IT YOURSELF

 Activity

Candle Burning Experiment

• Take a candle and fix it on a table. The candle is lighted. The candle will continue to burn due to continuously available fresh air providing the required oxygen for combustion.
• Now cover the burning candle by putting an inverted gas jar over it. After a short time, the candle stops burning and gets extinguished.

Observation: When the burning candle is covered with gas jar, then the candle takes away the oxygen necessary for burning from the air enclosed in the gas jar. After some time, when all the oxygen of air inside the gas jar is used up, then the burning candle gets extinguished. This proves that air is necessary for burning.
