Fire, or flame, is primarily an extremely hot gas, even hot enough to give off light. It is mainly composed of oxygen, carbon dioxide, nitrogen, and water vapor. In a solid, the molecules (what the objects are composed of) are very tightly packed together and are chemically bound, so it cannot change shape very easily. In a liquid, the molecules are not chemically bound, but they are packed very tightly together and interact strongly with their neighbors.

In a gas the molecules are not chemically bound, and are not even packed close together, in fact, they are so widely spaced that they hardly interact with each other at all.

Can you have solid or liquid fire?

Fire, as explained previously, is basically just burning gases. Sometimes, such as in a candle flame, glowing particles are suspended in the flame, causing the flame to be orange instead of blue. The gases in fire have to be something that will burn, or is flammable, such as hydrogen, methane, carbon dioxide etc. And so, you cannot liquify or solidify a flame.


Did You Know?

You can change the colour of the flame by burning different types of materials. Each element has its very own set of 'wavelengths' (colours) at which it radiates. These are usually seen in the yellow, or cooler part of the flame. Here you might see different colours like red or green instead of orange, because the differences between the elements is most significant at these cooler temperatures.

Whether fire is a tiny flame on the end of a candle or a huge roaring wall tearing down the forest, they are all basically the same, because all fire is made by a chemical reaction.

For anything physical to exist, it must have matter. Otherwise, fire, I suppose is one of the more basic forms of energy.

Fire is produced by a chemical reaction which releases energy from the substance which is burning. The process is started by bringing heat to the substance which is to be burned. This starts the chemical reaction. The chemical reaction produces more heat which maintains the fire.

Fire is produced by a chemical reaction which releases energy from the substance which is burning. The process is started by bringing heat to the substance which is to be burned. This starts the chemical reaction. The chemical reaction produces more heat which maintains the fire.

There is a chemical process taking place in a flame which releases heat and light. The heat which is released allows the combustion process to self perpetuate. The light which is released, gives the flame it's familiar glow. The shape of the flame is determined by various factors such as gravity and the amount of gases being released.

Fire consists of reacting, hot, volatile gases and reacting solid particles (soot) which emit heat and light to produce a flame.
There also by-products of the reaction within the flame such as carbon monoxide and carbon dioxide (carbon dioxide does not burn and so therefore does not contribute towards producing the heat and light, but any exhaust gases do contribute to the shape and character of the flame).

The exact chemical composition of fire depends on what is burning.

As an example, if we take a typical flame which we are familiar with, such as a candle flame, the burning gas is CH2O (Formaldehyde) and when this gas reacts with oxygen within the flame, it gets broken down into: carbon dioxide, carbon monoxide, carbon (particles), nitrogen and water (in gas form, or steam). Also, incandescent solid particles released from the burning wax (soot), produce the familiar red-orange glow. This red-orange glow is more prominent in a coal fire and not visible in a pure gas flame, due to the amount of solid particles being released.

But there are other chemical reactions that can produce fire, such as burning hydrogen in chlorine. This does not involve the gas CH2O.

So to summarize, a flame consists of a chemical reaction, hot gases, solid particals and exhaust gases. The chemical composition of these gases and solids vary depending of what is being burned.

Fire is the heat and light energy released during a chemical reaction, in particular a combustion reaction. Depending on the substances alight, and any impurities within, the color of the flame and the fire intensity might vary.

Fire itself is very difficult to define as it remains in various forms. Our own body is made of 5 basic elements, fire, earth, air, water & soul. Here what general people thinks fire with red/yellow/blue flame is not the fire but the heat or energy which helps to burn the undigested food and transform one energy to another within the body.

Likewise, Fire is a rapid oxidation process that creates light, heat, and ...

Here what general people thinks fire with red/yellow/blue flame is not the fire but the heat or energy which helps to burn the undigested food and transform one energy to another within the body.

Likewise, Fire is a rapid oxidation process that creates light, heat, and smoke, and varies in intensity. It is commonly used to describe either a fuel in a state of combustion (e.g., a campfire, or a lit fireplace or stove) or a violent, destructive and uncontrolled burning (e.g., in buildings or a ...

Fire, or flame, is primarily an extremely hot gas, even hot enough to give off light. It is mainly composed of oxygen, carbon dioxide, nitrogen, and water vapor.

fire is made of sub-atomic molecules that travel rapidly with kenetic energy and collide with each other making a flame wich is fire obviosly.

A fire or flame typically occurs when combustible airborne chemicals (fuels) oxidize (or burn) in such a way that heat is released (exothermic) and the electron activity or the temperature (incandescence) of the reaction emits visible light. The fire is the volume in the air where the chemicals are reacting in this way and emitting light. So, I guess the best answer I can give is that fire is made of vigorous chemical reactions.

Most fires also "feed" themselves because the heat produced by the flame drives more fuel particles from a solid or liquid source into the air.

Note that it is possible to have an invisible "fire" if the fuel burns in a way that does not produce visible light. Some alcohols burn with invisible flame - but that is not what people typically imagine when they think of fire. This kind of fire is also the region/volume of vigorous exothermic chemical reaction.

It is also possible to have fire without oxygen by combining other reactive chemicals, but in our atmosphere burning by oxidation is by far the most common phenomenon. It is also possible to have fire outside our atmosphere (no air), but the principles are essentially the same: mix stuff, chemical reaction makes heat and typically light.

"Fire" is just an energetic chemical reaction; oxidization. Google maxwell's Law's or check wiki for tech info.
