In summary, fire is a phenomenon that is often associated with oxidation and involves a self-sustaining reaction that produces heat and a flame. It has been viewed differently by different groups, with some considering it one of the four elements and others seeing it as a symbol of warmth and creativity. Ultimately, fire is a result of chemical reactions and can be described as incandescent gas.

Ah, a PHILOSOPHICAL question! To the alchemists of old, it's one of the four Elements. To mystics and magicians, it's the principle of warmth, expansion, creativity...the "Yod" of the four-fold unutterable Tetragrammaton (YHVH). But...perhaps you were after a less esoteric answer? ;) Fire, as we know it, is a phenomenon that often accompanies oxidation. There are two aspects to such oxidation that must occur for it to usually be called "fire": 1) The reaction must be self-sustaining, ie, it must liberate more heat than is required to initiate it. 2) It must produce a flame, which is caused by the luminosity of ions, and/or hot particles.evthis said:

FAQ: Is Fire Simply Incandescent Gas?
What is the chemical process of fire?
Fire is a chemical reaction that occurs when a combustible material (such as wood or gasoline) combines with oxygen in the air and releases heat and light energy. This process is known as combustion.
How does fire start?
Fire needs three elements to start: fuel, oxygen, and heat. When these elements combine in the right proportions, a fire can ignite. For example, a lit match provides the heat needed to ignite the fuel (paper or wood) and the oxygen in the air helps to sustain the fire.
Why does fire produce light and heat?
When a fire burns, it releases energy in the form of light and heat. This energy is a result of the chemical reaction between the fuel and oxygen. The light is produced as a result of the heated particles in the fire releasing energy in the form of photons, while the heat is a result of the transfer of thermal energy from the fire to its surroundings.
Can fire exist without oxygen?
No, fire cannot exist without oxygen. Oxygen is a vital component in the chemical reaction of fire, and without it, the fire would not be able to sustain itself. This is why fires cannot burn in environments with low levels of oxygen, such as outer space.
What are the different types of fire?
Fires can be classified into different types based on the type of fuel they burn. Some common types of fire include Class A (fires that involve ordinary combustible materials such as wood or paper), Class B (fires involving flammable liquids such as gasoline or oil), and Class C (fires involving electrical equipment). There are also more specialized types of fire, such as Class D (fires involving combustible metals) and Class K (fires involving cooking oils and fats).
