How did this fire happen?

"Fire is produced by burning matter, and its energy will be released in the form of light and heat. Combustible, ignition point and oxidant must coexist to catch fire. All three are indispensable. Fire is a plasma state between gas, solid and liquid.

Fire is composed of substances in plasma state, and plasma is the fourth state of substances (the other three are solid, liquid and gas) defined by British physicist Sir william crookes in 1879. "

Extended data

The visible part of a fire is called a flame. Particles can take on different shapes when they vibrate, and they can take on plasma (the fourth state, similar to gas) when the temperature is high enough. According to the burning substance and the purity of the flame, the color and brightness of the flame will vary.

Fire is one of the most important factors affecting the global ecosystem, and its positive role can maintain and promote the growth of various ecosystems. Humans use fire for cooking, heating, signaling, lighting and propulsion.
