fire is reacting gases and solids emitting visible and infrared light. A flame, which is different, is the visible part of a fire. Color and temperature vary depending on the materials involved. Portions of the flame are considered partial plasmas, ie ionized gas, but generally a flame is a region of exothermic chemical reaction of high enough temperature to emit visible light. there are 2 types of flames...a diffusion flame is when the oxygen and fuel mix, a premixed flame has the oxygen and fuel already mixed, resulting in a different flame...
