Question
How will you prove that oxygen supports burning?
✓
Answer
- Take three candles, two glass jars that can cover two candles but of different sizes and a watch.
- Light all the three candles at one time after fixing them on the table. Cover two candles with the jars. Leave one candle uncovered. Switch off the fan and close doors and windows. This will stop wind from blowing off the candles.
- After some time the candle covered with the small jar goes off first. Then the one with a bigger jar goes off. The candle in the open continues to burn. Thus, air supports burning.
