Open in App
Solution

  • Take 2 glass jars: Jar A and Jar B​

  • Jar A is covered with a lid while Jar B does not contain lid. ​

  • Place a candle in both jars. We can observe that the candle in Jar A extinguishes.​

  • Whereas, In glass jar B the candle remains lit for a longer time. This is because Jar B contains oxygen gas which is necessary for combustion of the candle​

Hence, it is proved that air is a supporter of combustion.
