n daily life, the vast majority of flames one encounters are those of organic compounds including wood, wax, fat, common plastics, propane, and
gasoline. The constant-pressure adiabatic flame temperature of such substances in air is in a relatively narrow range around 1950 °C. This is
because, in terms of stoichiometry, the combustion of an organic compound with n carbons involves breaking roughly 2n C–H bonds, n C–C bonds, and
1.5n O2 bonds to form roughly n CO2 molecules and n H2O molecules.
