 what is combustion ??

 

 

 

 

 

 

 

Dear user!

Combustion can be defined as burning of any substance in presence of atmospheric oxygen. The following reaction shows a combustion reaction wherein methane is burnt in atmospheric oxygen to form carbon dioxide and water vapour.

CH4 + 2O2 → CO2 + 2H2O

Combustion is an exothermic process i.e., the process is accompanied with the evolution of heat. The release of heat may or may not result in the production of light. Thus, two important things required for the process of combustion to take place are a fuel (combustible substance) and supporter of combustion (oxygen).

I hope, with this the concept of combustion becomes clear.

All the best!!

 A chemical process in which a substance reacts with oxygen to give off heat is called combustion. The substance , that burns in the presence of oxygen with the evolution of heat and light is called a combustible substance.

  1. The process of burning.
  2. A chemical change in the presence of oxygen, accompanied by the production of heat and light. Light may or may not be produced in every combustion reaction.

Combustion or burning is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species. The release of heat can produce light in the form of either glowing or a flame. Fuels of interest often include organic compounds (especially hydrocarbons) in the gas, liquid or solid phase.

In a complete combustion reaction, a compound reacts with an oxidizing element, such as oxygen or fluorine, and the products are compounds of each element in the fuel with the oxidizing element. For example:

CH_{4(g)} + 2O_{2(g)} to CO_{2(g)} + 2H_2O_{(g)}
