Hi Everyone,
What happened when I changed the size of the jar?
The smaller the jar the less seconds the candle did burn for.
Why did this happen?
The flame from the candle burned up all the oxygen in the jar and turned it into carbon dioxide. The candle went out because there was no oxygen left to keep it burning.
Was my prediction accurate?
Yes it was as the jars ran out of oxygen and the candle went out. The bigger the jar the more oxygen and the longer the candle burned for.
