Why Is Fire Hot?
Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. [1] At the ignition point of the combustion reaction, it produces flames. The visible portion of the fire is flame. It consists of carbon dioxide, water vapor, oxygen, and nitrogen. Sometimes, if the fire is too hot, the gases may become ionized to produce plasma. [2] Depending on the substances we burn and any impurities outside, the color of the flame and the fire's intensity will vary. [3] Orange and Yellow flame What is Ignition Temperature? The point where a body starts burning or catches fire is ignition. The ignition temperature for Iron is 1,315 °C, and for Hydrogen is at 535 °C. The fire is hot because: The chemical reactions involved in combustion release energy in the form of heat as they break down the molecular structure of the fuel. During combustion, the fuel molecules in the material break apart
