the fire u see is the wavelength of light emitted by energetic particles in the flame. for example, the yellow flame that u commonly see when lighting a match is caused by carbon(soot) particles that are glowing hot, thus emitting elcetromagnetic radiation with a wavelength in the region of yellow light. if u put a non-flammable surface like a pot over the flame, u would see that the soot deposits on the surface.
i heard that in space, fire burns in the shape of a fireball.....so it does not defy gravity on earth. it just rises because its less dense than the surrounding air.

Dennis L. Kirkpatrick on Smoke Defying Gravity.-10/24/14.
Albert Einstein says Gravity is the "Bending of Space" by an Item with Mass. Space is (-O-) Air. Smoke should rise to the top of Air, but if Space can bend like Einstein says, then Smoke should also Bend. Smoke is not hotter than Air even in the summer, it is just lighter. If smoke doesn't bend, then it defy 's Gravity. That means Gravity is something other than the Bending of Space. Has anyone ever seen what Smokes does "Out In Space". Maybe some Astronauts have seen it.

It cannot defy gravity; it obeys gravity. You need to ask a physic's professor for an exact answer. However, let me give it a try.

If you pour two liquids into a glass (where you can observe their behavior) the heavy one settles (eventually) to the bottom. Right? If there is a color difference, it is actually observable.

Fire gives energy to or accelerates air atoms / molecules. Thus they take more space than their unheated companions (is this called Brownian motion). They become so to say less heavy than before because they take more space. For this reason they try to ascend to a height where they attain a balance as far as weight with neighboring atoms / molecules.

A layman's explanation--don't trust it without asking a physic's professor.

Fire does not defy gravity. Heat rises, or more specifically, the air around the heat source rises. This is why fire travels up faster than it travels down.

1) Fire is not an element. It is just energy dispersed during combustive processes.

2) It does not defy gravity - if you produce a spark and watch its trajectory, it will fall to the ground.

first of all it is not an element it is a physical property (reaction)it is reactions fast enough to create emissions to heat our atmosphere to glow or emit at such a rate that we see it (visible light spectrum).and this excites the elements of the atmosphere and what ever is burning to expand -excite the atoms to energy levels that are greater than their surroundings.until they dissipate that energy, and this also includes compounds.compounds have individualistic characteristics also.

no, it is lighter than its surroundings, thus floating above air, the air is heavier, pushing down, forcing the fire up. it is not defiant to gravity. it is gravities ***** like we can not float, fire can not sink.

Heat rises.
Gravity is not being defied.
