Combustion or burning is a high-temperature exothermic chemical reaction between a fuel (carbon) and an oxidant, usually atmospheric oxygen, that produces carbon dioxide and other compounds, often gaseous mixture termed as smoke. Water is also produced along with smoke and other chemicals. Combustion also gives out heat energy.

Nitrogen does not participate in combustion.

An example of combustion is given below.

$C{H}_4\left(Methane\right)+2O_2⟶C{O}_2+2H_{2}O+Heat$
