Fire is neither a solid, liquid nor gas, but a different state of matter called plasma. Learn more about this fascinating phenomenon.
Oct 19, 2023 · Also, the laws of physics dictate that one cannot extract more energy out of a given substance without investing more energy into it. This fact eliminates the slightest possibility of fire being a solid, liquid, or gas. All types of fire gradually die out and cannot continue to exist in their natural state forever, unlike the above.

Jan 13, 2020 · Fire is made up of many different substances, so it is not an element. For the most part, fire is a mixture of hot gases. Flames are the result of a chemical reaction, primarily between oxygen in the air and a fuel, such as wood or propane. In addition to other products, the reaction produces carbon dioxide, steam, light, and heat.

Apr 20, 2022 · Like a gas, it expands to fill the volume in which it’s contained, whereas a flame does not. 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.

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 ...
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.

Add to collection. Fire is the visible effect of the process of combustion – a special type of chemical reaction. It occurs between oxygen in the air and some sort of fuel. The products from the chemical reaction are completely different from the starting material. The fuel must be heated to its ignition temperature for combustion to occur.
