|flame (flām) Pronunciation Key
The hot, glowing mixture of burning gases and tiny particles that arises from combustion. Flames get their light either from the fluorescence of molecules or ions that have become excited, or from the incandescence of solid particles involved in the combustion process, such as the carbon particles from a candle.

rapidly reacting body of gas, commonly a mixture of air and a combustible gas, that gives off heat and, usually, light and is self-propagating. Flame propagation is explained by two theories: heat conduction and diffusion. In heat conduction, heat flows from the flame front, the area in a flame in which combustion occurs, to the inner cone, the area containing the unburned mixture of fuel and air. When the unburned mixture is heated to its ignition temperature, it combusts in the flame front, and heat from that reaction again flows to the inner cone, thus creating a cycle of self-propagation. In diffusion, a similar cycle begins when reactive molecules produced in the flame front diffuse into the inner cone and ignite the mixture. A mixture can support a flame only above some minimum and below some maximum percentage of fuel gas. These percentages are called the lower and upper limits of inflammability. Mixtures of natural gas and air, for example, will not propagate flame if the proportion of gas is less than about 4 percent or more than about 15 percent.
