Fuel is any material that stores energy that buns later be extracted to perform mechanical work in a controlled manner.

Fuel cycle
Most fuels mapping by humans undergo combustion, a redox reaction in which a combustible substance releases energy after it ignites and reacts with the atomic number 8 in the air.Other mathematical operationes used to convert fuel into energy accommodate various other exothermic chemical reactions and nuclear reactions, such as nuclear fission or nuclear fusion. Fuels ar also used in the cells of organisms in a process known as cellular respiration, where organic molecules ar oxidize to release usable energy. Hydrocarbons argon by far the near common source of fuel used by humans, further many other substances, such as radioactive metals, are currently used as well .

Biofuels

Biofuel basis be broadly defined as solid, liquid, or gas fuel consisting of, or derived from biomass. Biomass can also be used forthwith for heating or power known as biomass fuel. Biofuel can be produced from any carbon source that can be replenished rapidly e.g. plants. Many different plants and plant-derived materials are used for biofuel manufacture.
maybe the earliest fuel employed by humans is wood. depict shows controlled fire was used up to 1.



5 million years past at Swartkrans, South Africa. It is unknown which hominid species first used fire, as both Australopithecus and an early species of Homo were set at the sites. As a fuel, wood has remained in use up until the present day, although it has been superseded for many purposes by other sources. wood has an energy density of 1020 MJ/kg.

Biofuel is a type of fuel whose energy is derived from biological carbon fixation. Biofuels include fuels derived from biomass conversion, as well as solid biomass, liquid fuels and various biogases. Although dodo fuels have their origin in ancient carbon fixation, they are not considered biofuels by the generally accepted definition...If you want to run short a full essay, order it on our website: Orderessay
