Science cannot precisely describe the true nature of fire, but to clear up the doubts of inquisitive minds, fire is most similar to plasma! Plasma resembles a gas more than any other state of matter, but it behaves very differently from a gas.

A burning candle. Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. [1][a] At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire.
But what we can conclude (for now) is that, of the fundamental states of matter, fire is most like a plasma. In fact, some very hot flames do contain plasma – when the energy inside them is sufficient to ionise enough of the air molecules. A classic example is the flame generated by burning acetylene in oxygen, which reaches an eye-watering ...

Is fire a solid, liquid or gas? - BBC Science Focus Magazine
The properties of a substance are the properties of a huge number of particles together. Solids: have a fixed shape and cannot flow, because their particles cannot move from place to place;
Mar 5, 2013 · All fires eventually burn themselves out, unlike solids, liquids, and gases, which can exist indefinitely in the same state.”. Most of fire’s energy output is in the form of heat. As the gas mixture warms, it also rises and gives the flame its familiar teardrop taper. “A flame holds its shape because chemical reactions happen at different ...

Jul 18, 2024 · Incomplete combustion produces soot, which is mainly carbon. Fire is mostly a state of matter called plasma. However, parts of a flame consist of solids and gases. The exact chemical composition of fire depends on the nature of the fuel and its oxidizer. Most flames consist of carbon dioxide, water vapor, nitrogen, and oxgen.
