The ancient Greeks and alchemists thought it was an element.alchemists (They also considered earth, air, and water to be elements.) Fire is made up of many different substances, so it is not an element, fire is a mixture of hot gases. Flames are the result of a chemical reaction, primarily between oxygen in air and a fuel producing carbon dioxide, steam, light, and heat. If the flame is hot enough, the gases are ionized and become yet another state of matter: plasma.

What are the 4 states of matter? Solid Liquid Gas Plasma

What the heck is plasma? closely related to gases the particles are neither atoms nor molecules, but electrons and positive ions.particles Plasmas can be formed at very high temperatures The resulting particles can then move freely, like the particles in a gas. found on Earth in the outermost atmosphere probably more prevalent in the universe than all of the other three states of matter. – The stars, comets' tails, and the aurora borealis are all plasmas. Because their particles are electrically charged, plasmas are greatly influenced by electric and magnetic fields.magnetic fields

Is that what’s in my “plasma” TV? A plasma display panel (PDP) Many tiny cells between two panels of glass hold a mixture of noble gases. The gas in the cells is electrically turned into a plasma which then excites phosphors to emit light.glassnoble gasesplasmaexcitesphosphorsemit – Phosphors (not the element phosphorus) are metallic compounds
