Fire. A burning candle. Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. [1][a] At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire.
When you pour water onto a fire, the heat of the fire causes the water to heat up and turn into steam. This is a very energy-intensive reaction, and it sucks away the heat (which is a form of energy) of the fire. This leaves the fire without enough energy to keep burning. Less significant is the role water can play in ‘smothering’ a fire ...
The fire generates winds of its own that are as many as 10 times faster than the ambient wind. It can even throw embers into the air and create additional fires, an occurrence called spotting. Wind can also change the direction of the fire, and gusts can raise the fire into the trees, creating a crown fire.

Mar 14, 2014 · Fires burn only when all that atomic shuffling releases enough energy to keep the oxidation going in a sustained chain reaction. More atoms released from the fuel combine with nearby oxygen. That releases more energy, which releases more atoms. This heats the oxygen — and so on. The orange and yellow colors in a flame appear when extra, free ...
Oct 7, 2011 · The fire fried the rats and fleas that carried Yersinia pestis, the plague-causing bacterium. 16. The Peshtigo Fire in Wisconsin was the second deadliest blaze in United States history, taking 1,200 lives — four times as many as the Great Chicago Fire. Both conflagrations broke out on the same day: October 8, 1871.
Jun 2, 2023 · The three components of fire are heat, fuel, and oxygen. Heat is required to raise the fuel to its ignition temperature. Fuel can be any combustible material such as wood, gasoline, or paper. Oxygen is necessary for combustion and is usually present in the air around us. The chemical reaction that occurs during combustion is known as oxidation.
