Detailed explanation-1: -Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

Detailed explanation-2: -When fuel burns, it reacts with oxygen from the surrounding air, releasing heat and generating combustion products (gases, smoke, embers, etc.). This process is known as oxidation.

Detailed explanation-3: -Combustion refers to the process where a substance burns in the presence of Oxygen, giving off heat and light in the process. You might have heard that certain substances are combustible whereas some are non-combustible.
