Combustion is the complete oxidation of organic compound into carbon dioxide and water molecules in the presence of oxygen gas whereas oxidation is the addition of oxygen in a compound or addition with an element. It is also defined as a reaction in which there is loss of an electron from an atom or ion. Combustion reactions involve heat and light whereas oxidation reaction does not involve heat. All combustion reactions are oxidizing since they absorb Oxygen for the reaction to take place but all oxidation reactions are not combustion reactions.
