In March retail sales 1 at constant prices were by 9. Compared with February retail sales decreased by 3. Introduction in March this year the state of epidemic threat, followed by the state of epidemic and the related significant reduction in retail trade in some commercial facilities substantially affected the volume of purchases and realized retail sales.

Coal is currently a major source of fuel for power generation, industrial heat, and, on a smaller scale, manufacture of coke and by-product coal tar. In the mid to long-term, anticipated increases in the cost of natural gas and petroleum relative to coal are expected to increase the incentive for expanded efforts to convert coal to ash-free, low-sulfur transportation fuels and, ultimately, gaseous fuels for domestic use see Chapter 3. As natural gas prices increase, substitution of gas from coal in natural gas-fired power generation plants may become economic. Advanced combined-cycle and fuel cell power generation technologies will also require the conversion of coal to clean gaseous fuels. In addition to the above major uses, economical use of clean gaseous and liquid products from coal can provide a source of feedstock for chemicals production.

Liquid fuels are combustible or energy-generating molecules that can be harnessed to create mechanical energy , usually producing kinetic energy ; they also must take the shape of their container. It is the fumes of liquid fuels that are flammable instead of the fluid. Most liquid fuels in widespread use are derived from fossil fuels ; however, there are several types, such as hydrogen fuel for automotive uses , ethanol, and biodiesel , which are also categorized as a liquid fuel. Many liquid fuels play a primary role in transportation and the economy. Liquid fuels are contrasted with solid fuels and gaseous fuels.

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. Other times the heat itself is valued for warmth, cooking , or industrial processes, as well as the illumination that comes with combustion. Fuels are also used in the cells of organisms in a process known as cellular respiration , where organic molecules are oxidized to release usable energy. Hydrocarbons and related oxygen-containing molecules are by far the most common source of fuel used by humans, but other substances, including radioactive metals, are also utilized.

Difference Between Solid, Liquid and Gas

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. Most solids are hard, but some like waxes are relatively soft. Many solids composed of ions can also be quite brittle.

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. By gaseous fuels, consideration is given to the storage state at ambient temperatures even though the fuel in usage can be in the liquid state. Unable to display preview.


its one state to another, i.e. from solid to liquid or gaseous state, liquid to gaseous state, The various advantages and disadvantages of solid fuels are given below: (a) What is the difference between natural and manufactured fuels?


Formation of Liquid Products at the Filtration Combustion of Solid Fuels

There are two main types of rockets: liquid-fuel and solid-fuel. Liquid-fuel rockets consist of a fuel and oxygen or other oxidizer in liquid state. They are combined in a combustion chamber and ignited. The fuel flow to the engine can be controlled, the amount of thrust produced can be regulated and the engine can be turned off or on as needed.

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.

 Шестьдесят четыре знака… Сьюзан кивнула: - Да, но они… - Она вдруг замерла. - Шестьдесят четыре буквы, - повторил Дэвид. - О мой Бог! - воскликнула Сьюзан.  - Дэвид, ты просто гений.

Стратмор пожал плечами: - Стандартный коммерческий алгоритм. Насколько я могу судить, пароль из шестидесяти четырех знаков. В полном недоумении Сьюзан посмотрела в окно кабинета на видневшийся внизу ТРАНСТЕКСТ.

Беккер огляделся: - Понимаю. Это ужасно. Простите, что я так долго до вас добирался. - Мне даже не сказали, что вы придете. Беккер поспешил переменить тему: - У вас на голове огромная шишка.


A solid can be classified as a substance that is rigid with low intermolecular spacing and high intermolecular forces, that binds all molecules within together.
