ker / ˈbəngkər/ • n. 1. a large container or compartment for storing fuel: a coal bunker. A fuel is a substance that releases energy. If fuel octane is too low for a given compression ratio, the fuel prematurely and spontaneously ignites too early and the fuel charge EXPLODES rather than BURNS resulting in incomplete combustion. A fuel is any compound that has stored energy. Gasoline is a product of petroleum refining that varies in composition and often includes additives such as antiknock agents, antioxidants, lubricants, and detergents. Did You Know? M.A. A fuel is any material that can be made to react with other substances so that it releases energy as heat energy or to be used for work. Petrochemistry is a branch of chemistry that studies the transformation of crude oil and ... Two of the fractions of distillation are fuel oil and naphtha, which are familiar to consumers. fuel definition: 1. a substance that is used to provide heat or power, usually by being burned: 2. anything that…. Naphtha is used in gasoline and also used as the primary source for petrochemicals. This energy is captured in chemical bonds through processes such as photosynthesis and respiration.

Chemistry Dictionary Definition of fossil fuels Substances consisting largely of hydrocarbons, derived from decay of organic materials under geological conditions of high pressure and temperature (metamorphism) include coal, petroleum, natural gas, peat and oil shale. (verb) An example of fuel is putting gas in your car. Compounds in the body such as glucose are broken down into simpler compounds to provide energy for metabolic processes. In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. The energy contained in the fuel is released when it burns. Kamrin, in Encyclopedia of Toxicology (Third Edition), 2014. Menu. Products from Oil. A commonly known example of diesel engines would be: school buses, construction machines, and public buses. NAICS: 32-5193 Ethyl Alcohol Manufacturing Proudly powered by Weebly Dictionary ! The most common form of oxidation is the direct reaction of a fuel with oxygen through combustion. Combustion is considered to be one of the first chemical reactions intentionally controlled by humans. Combustion is burning a fuel in oxygen, which gives out heat energy and is called an exothermic reaction. ∎ (bunkers) fuel for a ship. 1 is a straight-run middle distillate with a … However, the date of retrieval is often important. A substance that produces useful energy when it undergoes a chemical or nuclear reaction. Here is isooctane(C8H18), typical of th… The definition of fuel is anything that produces energy, power or heat. Energy is released during oxidation. It is also known as burning. 2. a reinforced undergroun…, Fossil fuels are buried deposits of plants and animals that have been converted to coal, petroleum, natural gas, or tar by exposure to heat and press…, Ethanol Background. In an engine cylinder, fuel are air … A fuel is a substance that releases usable energy either through: a nuclear reaction such as fission or fusion an oxidation-reduction reaction with an oxidiser In a combustion (burning) reaction the fuel … Alternative fuels tend to be made up of small, fairly simplemolecules; for example, here are schematic chemical diagrams (Cdenotes a carbon atom, H is hydrogen, and O is oxygen) of methane(CH4), the primary constituent of liquefiedor compressed natural gas, and propane(C3H8), the primary constituent of liquifiedpetroleum gas. Our main source of fuel is from fossil fuels. The compounds in this fuel include paraffin, isoparaffins, naphthenes, olefins and aromatic hydrocarbons. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list. Fuel cell, any of a class of devices that convert the chemical energy of a fuel directly into electricity by electrochemical reactions. Fuel is defined as to give energy or power. A fuel cell is an electrochemical system combining hydrogen and oxygen to generate energy, with the by-products of water and heat. In a spark-ignition engine, using a fuel with too low an octane rating can lead to pre-ignition and engine knock, which can cause engine damage. SIC: 2869 Industrial Organic Chemicals, not elsewhere classified To burn fuel properly. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. Most are saturated and contain 4 to 12 carbon atoms per molecule. Some fuels (for example uranium) release energy from nuclear reactions.Most fuels release their energy by reacting with oxygen in the air ().. A fuel will burn more rapidly and release energy at a faster rate if it is supplied with pure oxygen instead of air. Fuel such as coal, wood, oil, or gas provides energy when burned. Fuel definition is - a material used to produce heat or power by burning. Learn more. A substance that produces useful energy when it undergoes a chemical or nuclear reaction. A fuel cell resembles a battery in many respects, but it can supply electrical energy over a much longer period of time. Petroleum fuels are blends of lots of different chemical species;in general, the molecules of a liquid petroleum fuel are pretty bigand complex. An example of fuel is gasoline. You may need to download version 2.0 now from the Chrome Web Store. A fuel cell can be described as an electrochemical cell which, through an electrochemical reaction, generates electrical energy from the fuel. It consists of hydrocarbons having longer carbon chains where they have carbons from 8 to 21. the tendency for preflame reactions is high for straight chain hydrocarbons, medium for branched hydrocarbons, and low for aromatics. The octane number for a test gasoline represents the percentage by volume of isooctane (2,2,4-trimethylpentane) in a reference fuel consisting of the mixture of isooctane and heptane that would be necessary to match the test fuel's knocking tendency. Combustion is considered an exergonic or exothermic chemical reaction. CiteScore values are based on citation counts in a range of four years (e.g. Compounds in the body such as glucose are … Octane is a chain of eight contiguous carbon atoms. Biofuel definition is - a fuel (such as wood or ethanol) composed of or produced from biological raw materials. Both are hydrocarbons. Diesel oil is a complex mixture produced by the distillation of crude oil. The recent invention of nuclear technology means now even nuclear energy may be released due to nuclear fission or fusion.
