Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Slower oxidative processes like rusting or digestion are not included by this definition.. Fire is hot because the conversion of the weak double bond in molecular oxygen, O 2, to the stronger bonds in the combustion products carbon dioxide and water ...
Chemistry of a Fire The Fire Tetrahedron Fires start when a flammable and/or a combustible material, in combination with a sufficient quantity of an oxidizer such as oxygen gas or another oxygen-rich compound (though non-oxygen oxidizers exist that can replace oxygen), is exposed to a source of heat or ambient temperature above the flash point for
Fire is the result of a chemical reaction called combustion.At a certain point in the combustion reaction, called the ignition point, flames are produced.Flames consist primarily of carbon dioxide, water vapor, oxygen, and nitrogen.
A side effect of these chemical reactions is a lot of heat. The fact that the chemical reactions in a fire generate a lot of new heat is what sustains the fire. Many fuels burn in one step. Gasoline is a good example. Heat vaporizes gasoline and it all burns as a volatile gas.
Fire is burning, which is combustion, and combustion is a type of oxidation reaction. Oxidation means combined chemically with oxygen . Oxidation is an exothermic reaction, meaning it gives releases heat energy. The chemical equations for the oxidation of carbon and hydrogen are:
This chemistry demonstrations are intended to educate and should only be performed by qualified, responsible professionals. Projects involving fire should not be attempted by children or anyone incapable of following the safety protocols. Fire is naturally hot and able to spread.
What's the chemistry and physics of a flame? This week, learn about the beautiful science happening inside a flame! Michael Faraday's Christmas lectures on candle chemistry:
What is fire? This video takes you on a tour of a combustion reaction, revealing what a flame is, how light and heat are generated, and what it is that carries the heat that we feel emanating from ...
But fire is really something completely different. Earth, water and air are all forms of matter -- they are made up of millions and millions of atoms collected together. Fire isn't matter at all. It's a visible, tangible side effect of matter changing form-- it's one part of a chemical reaction.
The fire itself represents chemical changes, but heat rising is a physical property of matter. It's physics. A lot of the behavior of fire is physics because of the heat and the movement of air ...
