When a substance combines with oxygen and energy is emitted in the form of heat and light, this process is called combustion.
There are two types of combustion.
1) Complete Combustion : It is a type of combustion in which fuel is quickly react with high amount of oxygen forming carbondioxide, water, heat and light.
2) Incomplete combustion : It is a type of combustion in which fuel is react with low amount of oxygen forming carbonmonoxide, carbon and water.
Explanation: Combustion is a reaction in which a substance (a fuel) reacts with oxygen to produce heat energy. Another name for combustion is burning. Combustion can be complete or incomplete: complete combustion takes place in the presence of unlimited supply of oxygen in which the substance is completely oxidized leaving water and carbon dioxide as by-products. Incomplete combustion occurs in the presence of limited quantity of oxygen in which the substance is not completely oxidized. The byproducts are carbon monoxide and soot.
Answer: The average kinetic energy in an object or substance tells us its mass. Kinetic energy has a direct relationship with mass, meaning that as mass increases so does the kinetic energy of an object.
