Coal (fuel source)

Coal is primarily used for electricity generation, as it is burned to produce steam that powers turbines connected to generators. It is also used in industrial processes such as steel production and cement manufacturing. Additionally, coal is used for heating in residential and commercial buildings.

Coal is a sedimentary rock formed from the remains of plants, while tektites are natural glass objects formed from terrestrial debris ejected during meteorite impacts. Coal is typically dull black in color and has a layered texture, while tektites are usually black, green, or brown and have a smooth, rounded surface. Additionally, coal is opaque and can be scratched with a knife, whereas tektites have a glassy luster and are harder than steel.

Coal dust burns fast because it has a high surface area-to-volume ratio, allowing more oxygen to react with the dust particles simultaneously. This increased oxygen availability accelerates the combustion process, causing coal dust to burn quickly.

Coal, oil, and amber are not considered minerals because they are organic in origin, formed from decayed plants and animals rather than being inorganic solid substances with a crystalline structure like minerals. Additionally, coal, oil, and amber are composed of complex organic compounds rather than the simple chemical composition typically associated with minerals.

Coal is burned in power plants to heat water and produce steam, which drives turbines connected to generators to produce electricity. This process is known as coal combustion. The electricity generated is then sent out for distribution through power lines to homes and businesses.

Coal is typically stored in stockpiles or silos near the mine site. These stockpiles are designed to keep the coal dry and prevent it from catching fire. Some coal may also be transported directly to power plants or other customers for immediate use.

The need for coal increased primarily due to the Industrial Revolution, which led to a higher demand for energy sources to power factories and machinery. Coal became a popular choice because it was abundant, cheap, and provided a reliable source of energy for the growing industrial economy.

Coal is a fossil fuel composed mainly of carbon, so it does not have an atomic number since it is not an element. It is made up of complex organic compounds formed from plant material over millions of years.

One type of energy released and not useful when coal is burnt is thermal energy in the form of waste heat. This energy is often lost to the environment in the process of burning coal and is not harnessed for productive use.

The percentage of carbon in coal can vary widely, but it typically ranges from about 50% to 90%. The carbon content is a key factor in determining the quality and energy content of the coal.

The energy change in burning coal is a chemical reaction in which the potential energy stored in the chemical bonds of coal is converted into heat and light energy. This process releases heat and other byproducts, such as carbon dioxide and sulfur dioxide, into the atmosphere.

The mass of coal can vary depending on the type and size of the coal. On average, coal has a density of about 1.3 to 1.5 grams per cubic centimeter. So, for example, a cubic meter of coal would have a mass of about 1300 to 1500 kilograms.

When coal is burned, the carbon in the coal combines with oxygen in the air to form carbon dioxide. This carbon dioxide is released into the atmosphere as a greenhouse gas, contributing to climate change.

Burning coal, oil, and gas releases carbon dioxide (CO2) into the atmosphere, contributing to global warming and climate change. In addition, these processes can release other pollutants such as sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter, which can harm human health and the environment. Methane (CH4) is also released during the extraction and burning of these fossil fuels, which is a potent greenhouse gas.

Also it is an industrial chemical, which is baked to form coke, and liberates , ammonia, hydrogen sulphide, methane, sulphur dioxide, which are collected and further used industrially,.

Coal scarcity refers to a situation where the supply of coal is insufficient to meet the demand for energy production. This can lead to increased prices, energy shortages, and a greater reliance on alternative sources of energy. Coal scarcity can be influenced by factors such as depletion of coal reserves, production disruptions, and changes in energy policies.

Huge deposits of carbon were stored over millions of years through processes like sedimentation and burial of organic matter, leading to the formation of coal, oil, and natural gas. These fossil fuels contain large amounts of carbon that were extracted from the atmosphere by plants and other organisms during their growth and then preserved underground.

Coal is formed when plant material from ancient times becomes fossilized. The material becomes buried by sediments, so that oxygen is excluded and it doesn't rot. As the sediments build up the plant material is subjected to increasing pressure and may be heated. All this causes the carbon compounds making it up to change, largely to hydrocarbons and carbon. The fossilization process is quite random. The initial plant material can vary, though often it was tree ferns from the carboniferous era, around 300 million years ago. Another important factor is how old the coal deposits are. The older they are, in general the greater the proportion of compounds which are converted to carbon. This tends to make hard, black coals such as anthracite which burn relatively cleanly.

During the burning of coal, chemical energy stored in the coal is converted into thermal energy in the form of heat. This heat energy can be used to generate steam, which in turn drives turbines to produce electricity.

Coal can form in swamps and marshes that have abundant plant material, deposition of sediments, and lack of oxygen. The plant material decays and undergoes chemical and physical changes over millions of years, eventually forming peat, which then transforms into coal under high pressure and heat.

The residue from coal is known as coal ash or fly ash. It is a fine, powdery material that is generated when coal is burned in power plants. Coal ash can contain heavy metals and other toxic substances, posing environmental and health risks if not properly managed.

The fine coal dust is much more combustible than large lumps of coal. Large lumps of coal takes time for the flames to begin burning it efficiently - so heat takes longer to build up in the furnace.

Coal forms from the remains of plants that lived and died millions of years ago. These plants accumulated in swamps and other wet environments, where the lack of oxygen prevented their complete decay and allowed them to transform into coal over time.

The energy input of burning coal is the heat energy released during the combustion process. This heat energy can be used to generate electricity or heat buildings.
