Fire - Navo

• Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products.
• The flame is the visible portion of the fire. If hot enough, the gases may become ionized to produce plasma.
• Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning.
• Fires start when a flammable or a combustible material, in combination with a sufficient quantity of an oxidizer such as oxygen gas or another oxygen-rich compound (though non-oxygen oxidizers exist), is exposed to a source of heat or ambient temperature above the flash point for the fuel/oxidizer mix, and is able to sustain a rate of rapid oxidation that produces a chain reaction.
• Fire has been used by humans for cooking, generating heat, light, signaling, and propulsion purposes.
