Question

10. What will happen when we cover the burning candle with a glass jar. State
three necessary conditions which are required for a candle to keep on burning.


​

Answer 1

This happens because oxygen in the air inside the glass tumbler is utilized in burning the candle. All the oxygen gets converted into carbon dioxide. Carbon dioxide does not support burning and hence candle stops burning.

Answer 2

Answer:

The burning candle will stop burning.

Explanation:

Any item to burn, oxygen is necessary and in a glass jar there is no space to pass oxygen. Hence, the candle will stop working.
