WebMay 14, 2002 · The fact that the chemical reactions in a fire generate a lot of new heat is what sustains the fire. Many fuels burn in one step. Gasoline is a good example. Heat vaporizes gasoline and it all burns as a volatile gas. There is no char. Humans have also learned how to meter out the fuel and control a fire.

Fire emits heat and light because the chemical reactionthat produces flames is exothermic. In other words, combustion releases more energy than is needed to ignite or sustain it. In order for combustion to occur and flames to form, three things must be present: fuel, oxygen, and energy (usually in the form of … See more Fire is the result of a chemical reaction called combustion. At a certain point in the combustion reaction, called the ignition point, flames are produced. Ordinarily, flames consist primarily of carbon dioxide, water … See more However, fire does not actually require oxygen. Yes, the oxidizer most often encounteredisoxygen, but other chemicals also work. For example, burning hydrogen with chlorine as an … See more While all fire produced heat or is exothermic, some fires are cooler than others. So-called cold fire refers to a fire that burns below a … See more In a candle flame or small fire, most of the matter in a flame consists of hot gases. A very hot fire releases enough energy to ionize the gaseous atoms, forming the state of matter called plasma. Examples of flames that contain … See more WebFeb 28, 2024 · Carbon capture and use may provide motivation for the global problem of mitigating global warming from substantial industrial emitters.
