Question

As u can see the Candle farthest to the right was still burning after 12 seconds but the other ones went out why come the candle in the biggest jar burn the longest rather than the ones in the smaller jar?

Answer 1

The rightmost jar has the maximum volume among the three jars, containing the maximum Oxygen.

We know that more amount of Oxygen helps burn for more time.

For this reason, the candle in the farthest right was burning more.

A combustion reaction is a major class of chemical reactions referred to as burning. Good signs that you are dealing with a combustion reaction include the presence of Oxygen as a reactant and CO2, water, and heat as products.

The visual evidence is the light and the heat in form of the flame of fire.
