Why does fire rise upwards?

Hot gases have less density than cooler gasses and so they "float" (move upwards). What you see of fire are hot gases that are oxidizing and giving off light.Experiment:An interesting experiment is to put a short candle in a jar with a tight lid. Light the candle and put on the lid, measure the time it takes for the candle to "suffocate".DON'T burn your fingers now!Repeat the experiment but this time as soon as the lid is on tight drop the jar (preferably from over two meters) and see if the flame does not go out much quicker because the hot gasses will not "float" up in the accelerating frame of reference that is the inside of the jar.Make sure the jar does not break by having something soft (a pillow or jumble of rags in a basket) where the jar lands.
