== Flames generally "go up" because the hot gas produced due to combustion, being

much hotter and lighter than the surrounding air, have a lower density and hence rise

against the downward pull of gravity. == Fire burns upwards because as the heat grows then there is less oxygen in the air and as a result then the fire has to find more oxygen so that it can continue to burn

Why fire moves up in direction?

Fire moves upward due to the natural convection process. As the fire heats the surrounding air, it becomes less dense and rises, creating a flow of air upwards. This convection current carries the flames and heat upwards, which is why fire tends to move in an upward direction.


Can fire burn on water?

Yes, fire can burn on water if certain conditions are met, such as using a flammable substance that can float on the water's surface.


Can fire burn on top of water?

Yes, fire can burn on top of water if certain conditions are met, such as using a flammable substance that can float on the water's surface.


How can you enhance the intensity of a fire to make it burn hotter?

To enhance the intensity of a fire and make it burn hotter, you can increase the supply of oxygen, add more fuel, or use a fire accelerant. These actions can help create a more intense and hotter burning fire.


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.
