Solution
Procedure:
Take two burning candles and place them on a table. Now cover one candle with an inverted glass tumbler.
Observation:
- It will be noticed that the candle covered with an inverted glass tumbler blows out after some time, whereas the other candle continues to burn.
- This happens because there is no air inside the glass tumbler.
- However, the air initially present in the glass tumbler is used up in burning.
- This shows that air supports burning.
