火

Also known as fires

Fire is the rapid oxidation of a fuel in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Flames, the most visible portion of the fire, are produced in the combustion reaction when the fuel reaches its ignition point temperature. Flames from hydrocarbon fuels consist primarily of carbon dioxide, water vapor, oxygen, and nitrogen. If hot enough, the gases may become ionized to produce plasma. The color and intensity of the flame depend on the type of fuel and composition of the surrounding gases.

OverviewAI-generated

Fire is a physical phenomenon and a form of combustion. It produces thermal energy as an effect and results in heat and ash. The process involves parts such as flame and smoke.

Common uses for fire include roasting and cooking. It is represented by the Unicode character 🔥. The subject appears in the Commons category "Fire" and the gallery titled "Fire." Its main category is listed as Category:Fire.

Fire is described by sources including the Gujin Tushu Jicheng and the Encyclopædia Britannica 11th edition. It is part of the Wikipedia:List of articles all languages should have and the Wikipedia:Vital articles/Level/4 focus lists. A template for the topic is available as Template:Fire. The subject is referenced by 1,316 other encyclopedia articles.

火（英語：Fire）是物質燃燒過程中所進行的強烈氧化反應，其能量會以光和熱的形式釋放，並會產生大量的生成物。緩慢的氧化反應，例如生锈或消化不在上述的定義中。火的可见部分称為焰，可以隨著粒子的振動而呈現不同的形狀，在温度足够高时能以等离子体（第四態，類似氣體）的形式出現。依燃燒的物質及純度不同，火焰的顏色和亮度也會不同。火必須有可燃物、夠高的熱或溫度、氧化劑及化學物四項並存才能生火，根據質量守恆定律，火不會使被燃燒物的原子消失，只是透過化學反應轉變了被燃燒物的分子型態。火失控時，常常稱作失火或火災。所有已知的人類社會都已知用火，火的使用是普世文化通則之一；而在現代人演化出來之前，古代的人屬生物，也就是現代人類在生物學上的祖先，如直立人，可能在一百萬年前到一百五十萬年前或更早，就已知用火。火是影響全球生態系統的重要因素之一，火的正面影響可以維持各種生態系統以及刺激其成長。人類用火來烹調、生熱、產生訊號、照明及推進等。火的負面影響包括水體污染、、空氣污染及對生命財產的危害。而造成全球溫度升高的溫室效應，其原因之一就是來自燃燒化石燃料產生的二氧化碳。
