Plasma
- In a candle flame or small fire, most of the matter in a flame consists of hot gases. A very hot fire releases enough energy to ionize the gaseous atoms, forming the state of matter called plasma.

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.
Jun 25, 2020 · Fire is an exothermic chemical reaction that produces energy in the form of heat and light. ‘The elements of fire’ explains its composition through a ‘triangle’ of heat, fuel, and oxygen, and the processes of ignition and combustion.
Oct 7, 2024 · Fire, rapid burning of combustible material with the evolution of heat and usually accompanied by flame. It is one of the human race’s essential tools, control of which helped start it on the path toward civilization. The original source of fire undoubtedly was lightning, and such fortuitously.

The heat of the flame will keep remaining fuel at ignition temperature. The flame ignites gases being emitted, and the fire spreads. As long as there is enough fuel and oxygen, the fire keeps burning. Fuel + oxygen (from the air) = combustion products (mainly CO 2 + H 2 O) + heat energy.
What we know for sure is that fire is the visible effect of combustion – an exothermic chain reaction requiring the fire triangle: oxygen, heat and some type of fuel. Combustion resulting in fire can only occur between gases (liquid or solid fuels must first be vaporised for there to be a flame) and that gives us our first clue as to how to ...

Mar 14, 2014 · The process, called pyrolysis, releases atoms and energy. Unbound atoms form a hot gas, mingling with oxygen atoms in the air. This glowing gas — and not the fuel itself — produces the spooky blue light that appears at the base of a flame.
Fire is a chemical reaction that converts a fuel and oxygen into carbon dioxide and water. It is an exothermic reaction, in other words, one that produces heat.
