Fire is the rapid oxidation Redox describes all chemical reactions in which atoms have their oxidation number (oxidation state) changed. This can be either a simple redox process such as the oxidation of carbon to yield carbon dioxide or the reduction of carbon by hydrogen to yield methane (CH4), or it can be a complex process such as the oxidation of sugar in the human body of a material in the chemical process of combustion Combustion or burning is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species. The release of heat can result in the production of light in the form of either glowing or a flame. Fuels of interest often include organic compounds in the gas, liquid or, releasing heat In physics and thermodynamics, heat is the process of energy transfer from one body or system due to thermal contact, which in turn is defined as an energy transfer to a body in any other way than due to work performed on the body, light Light is electromagnetic radiation, particularly radiation of a wavelength that is visible to the human eye . In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not, and various reaction products A product is a substance that forms as a result of a biological- or chemical reaction. While the end product of some chemical reactions may be the result of a relatively rapid reaction, nanoseconds to seconds, chemical equilibria in complex systems may require years or even centuries to be established. For example, equilibria in groundwater.[1] Slower oxidative processes like rusting Rust is a general term for a series of iron oxides, usually red oxides, formed by the reaction of iron and oxygen in the presence of water or air moisture. Several forms of rust are distinguishable visually and by spectroscopy, and form under different circumstances. Rust consists of hydrated iron oxides Fe2O3·nH2O and iron(III) oxide-hydroxide ( or digestion are not considered to be part of this definition.
The flame A flame is the visible (light-emitting) gaseous part of a fire. It is caused by a highly exothermic reaction (for example, combustion, a self-sustaining oxidation reaction) taking place in a thin zone. If a fire is hot enough to ionize the gaseous components, it can become a plasma is the visible portion of the fire and consists of glowing hot gases.
If hot enough, the gases may become ionized to produce plasma In physics and chemistry, plasma is a gas in which a certain portion of the particles are ionized. The presence of a non-negligible number of charge carriers makes the plasma electrically conductive so that it responds strongly to electromagnetic fields. Plasma therefore has properties quite unlike those of solids, liquids, or gases and is.[2] Depending on the substances alight, and any impurities outside, the color Color or colour is the visual perceptual property corresponding in humans to the categories called red, yellow, blue and others. Color derives from the spectrum of light (distribution of light energy versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of of the flame and the fire's intensity The factor π is a result of the fact that intensity is defined to exclude the effect of reduced view factor at large values θ; note that the solid angle corresponding to a hemisphere is equal to 2π steradians might vary. Fire in its most common form can result in conflagration Conflagration is an uncontrolled burning that threatens human life, health, property or ecology. A conflagration can be accidentally or intentionally created . Arson can be accomplished for the purpose of sabotage, diversion, and also can be the consequence of pyromania. During conflagration the property is destroyed by fire. Sometimes the, which has the potential to cause physical damage through burning Combustion or burning is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species. The release of heat can result in the production of light in the form of either glowing or a flame. Most fuels of interest are organic compounds in the gas, liquid or solid and can occasionally result in a phase transition A phase transition is the transformation of a thermodynamic system from one phase or state of matter to another in the affected mass if the temperature of the flame is hot enough.
Fire has been used by humans for cooking, generating heat, signaling, and propulsion purposes.
