Comparison Between Solid Liquid And Gaseous Fuels Pdf
File Name: comparison between solid liquid and gaseous fuels .zip
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. The concept was originally applied solely to those materials capable of releasing chemical energy but has since also been applied to other sources of heat energy such as nuclear energy via nuclear fission and nuclear fusion. The heat energy released by reactions of fuels is converted into mechanical energy via a heat engine.

7.2: Solids, Liquids, and Gases
Everything that surrounds us, such as air, food, water, plants, animals, vehicles, clothes and so forth is made up of matter. The matter is a collection of particles and is anything that has mass and occupies space. There are three fundamental states of matter, i. The size and shape of a solid object is definite. Nevertheless, if we talk about the other two states of matter, that is liquid and gas, then liquids flow to take the shape of the beaker and gases diffuse to fill the available volume completely. The main difference between solid, liquid and gas lies in their properties, which we are going to discuss in this article.

Applied Chemistry pp Cite as. Fuels are conveniently classified as solids, liquids, and gaseous fuels. Solid fuels include peat, wood, and coal and can encompass solid rocket fuels as well as metals. The earliest fuels used by man were nonfossil fuels of wood and oil from plants and fats from animals. The windmill and water wheels were other sources of energy.

Salgansky, V. Kislov, S. Glazov, M. Yields of liquid and gaseous products of the filtration combustion of cellulose, wood, peat, coal, and rubber have been investigated. Experiments have shown that the gasification of solid fuels in the regime with superadiabatic heating yields liquid hydrocarbons with quantity and quality, which are close to those produced using other methods, for example, by pyrolysis.
Learning Objectives. Solids and liquids are collectively called condensed phases because their particles are in virtual contact. The two states share little else, however. In the solid state, the individual particles of a substance are in fixed positions with respect to each other because there is not enough thermal energy to overcome the intermolecular interactions between the particles. As a result, solids have a definite shape and volume.
Applied Chemistry pp Cite as. The combustion process is usually an oxidation reaction involving oxygen and the oxidant and is in many cases in the gaseous state. Thus, the burning candle or the alcohol burner are examples of solid and liquid fuels burning in the gaseous state. Coal however does not volatilize and the combustion of many solids, including some plastics, occurs at the surface.
