By which matter fire is made up of which burns everything and it can be classified under which state of matter?
Answers
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. If the flame is hot enough, the gases are ionized and become yet another state of matter: plasma. Burning a metal, such as magnesium, can ionize the atoms and form plasma. This type of oxidation is the source of the intense light and heat of a plasma torch.
While there is a small amount of ionization going on in an ordinary fire, most of the matter in the flame is a gas, so the safest answer for "What is the state of matter of fire?" is to say it's a gas. Or, you can say it's mostly gas, with a smaller amount of plasma.
The ancient Greeks and alchemists thought that fire was itself an element, along with earth, air, and water. However, the modern definition of an element defines it by the number of protons a pure substance possesses. Fire is made up of many different substances, so it is not an element.
