Is fire a chemical or physical reaction?

Is fire a chemical or physical reaction?

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.

What is the chemical of fire?

Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma.

What is the chemical reaction that creates fire?

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.

Is fire a physical thing?

Fire is not a physical thing. Any fire generated is a product of a chemical reaction that releases primarily heat and light and not through a physical…

Is burning a fire a physical change?

Burning of wood is a chemical change as new substances which cannot be changed back (e.g. carbon dioxide) are formed. For example, if wood is burned in a fireplace, there is not wood anymore but ash. Other examples include burning of a candle, rusting of iron, baking a cake, etc.

How did make fire?

The chemical reaction of oxygen and a fuel source we know as fire has been around as long as oxygen and sources of fuel have been around. When lightning would strike a forest and create a fire, it probably intrigued and amazed them.

What are the chemical processes in fire?

Fire is a chemical reaction in which energy in the form of heat is produced. When forest fuels burn, there is a chemical combination of the oxygen in the air with woody material, pitch and other burnable elements found in the forest environment. This process in known as Combustion . Combustion is a chain reaction chemically similar to photosynthesis in reverse.

How does chemical reaction help fire?

Heat is released when chemical bonds are broken and formed during chemical reactions. Since these reactions are ongoing, combustion releases more heat than is needed to sustain a fire. This is what makes a fire self-perpetuating, and also what makes it hot.

What is the chemical formula for fire?

The basis of fire is the physics and chemistry of combustion. In a simple form the chemical equation for combustion can be illustrated as. (C6H10O5)n + O2 + kindling temperature –> CO2 + H2O + heat.

What is the chemical equation to fire?

Chemical formula of fire is: CH4(O.H.)(OH.)(CH3.)(O.)2(O2)(HCO.)(M.)(CxHx.) It’s highly reactive radical species.
