A flame burns upwards because the heat energy generated in the burning process heats up the air around the flame, which reduces its density .This hot air around the flame then starts rising up and the surrounding colder heavier air rushes down into its place, accelerating the hot air upwards, which in turn causes the flame to shoot up.

Answer for the Question of the Week

Steam comes out of the mouth on cold days because normal air that we breathe out every day is partially composed of water vapour, however we don’t see this vapour until the temperature drops. So when the vapour that’s in body temperature goes out to the cold environment ,it condenses and forms what appears as steam.
