Visible, gaseous part of a fireA flame is the visible, gaseous part of a fire1. It is caused by a highly exothermic reaction taking place in a thin zone1. Flames can be hot enough to have ionized gaseous components of sufficient density to be considered plasma1. Flame propagation is explained by two theories: heat conduction and diffusion2. Flames are streams of hot, burning gas from something on fire3. The flame heats any surrounding fuel so it releases gases as well.

Flame - Wikipedia
Color and temperature of a flame are dependent on the type of fuel involved in the combustion, as, for example, when a lighter is held to a candle. The applied heat causes the fuel molecules in the candle wax to vaporize (if this process happens in inert atmosphere without oxidizer, it is called pyrolysis). In this state they can then readily react with oxygen in the air, which gives off enough heat i…
