Combustion in a fire produces a flame, and the heat produced can make combustion self - sustaining . Combustion is often a complicated sequence of elementary radical reactions . Solid fuels, such as wood, first undergo endothermic pyrolysis to produce gaseous fuels whose combustion then supplies the heat required to produce more of them . Combustion is often hot enough that light in the form of either glowing or a flame is produced . A simple example can be seen in the combustion of hydrogen and oxygen into water vapor, a reaction commonly used to fuel rocket engines . This reaction releases 242 kJ / mol of heat and reduces the enthalpy accordingly (at constant temperature and pressure): </P> <Dl> <Dd> 2H 2 (g) + O 2 (g) → 2H 2O (g) </Dd> </Dl>
