Coal (fuel source)

Ah, coal is a beautiful thing, isn't it? Its chemical formula is quite simple, my friend. Coal is primarily made up of carbon, so its chemical formula is C, which stands for carbon. Just like how we mix colors on our palette to create a masterpiece, coal's composition of carbon creates its unique and useful properties.

Coal is combusted, to generate heat

Heat is used to generate steam, in a boiler, under pressure.

The pressurised steam then drives a turbine.

The turbine is rotating, and co-shafted to the generator.

The generator is a rotating magnet inside a coil of wire.

The rotating magnet inside the coil of wire induces an electric current in the wire.

Coal is an impure mixture of carboniferous compounds. It can be converted to coke , which is an impure form of carbon.

NB A Nuclea power station does exactly the samer, except that nuclear changes in the atoms generate heat to make the pressurised steam.

Oh, dude, you call them a coal miner. Like, they're out there in the mines, digging up that black gold, probably covered in soot and living that hard-knock life. But hey, someone's gotta do it, right?

The sun's energy is stored in coal and other fossil fuels through a process called photosynthesis. During photosynthesis, plants capture sunlight and convert it into chemical energy through the synthesis of glucose. Over millions of years, this stored energy is preserved in the form of carbon-rich compounds as plants and other organic matter decompose and are compressed underground, forming coal and other fossil fuels. When these fuels are burned, the stored energy is released as heat and light.

'Peat' is coal in the natural making.

However, the next stage of formation is 'lignite';

No, but it once was. Coal is produced by pressure in the earth and it once was was plants and animals millions of years ago. Oil is produced the same way.

Coal is sprayed with water to suppress dust and reduce the risk of fires or explosions. Coal dust can be highly flammable and can ignite easily, posing a safety hazard in coal mines, power plants, and transportation. By spraying water on coal, the dust particles are weighed down and kept moist, minimizing the risk of combustion.

Coal is not just a rock; it is a combustible sedimentary rock made up primarily of carbon, along with various other elements. When coal is exposed to heat in the presence of oxygen, a chemical reaction known as combustion occurs. This process breaks down the carbon molecules in coal, releasing energy in the form of heat and light. Therefore, coal burns due to the combustion process, which releases the stored energy within its carbon structure.

Well, isn't that just a happy little question! All three of these folks use their hands to do their work. The coal miner digs with their hands, the dentist uses their hands to care for teeth, and the guitar player strums those strings with their hands. Each one brings joy and skill to their craft in their own special way.

'Coal' is a hard black shiny carboniferous rock.

When combusted with oxygen it will release heat(Energy). It also releases carbon dioxide, sulphur dioxide, hydrogen sulphide amongst other gases.

The resultent solid in impure carbon , known as 'coke'.

Chemical energy is transferred to electrical energy! :) :p

Coal rocks or more usually 'coal'. is a black shiny carboniferous rock.

It can be combusted to produce heat, carbon dioxide and other gases.

Historically, it was used to heat houses, factories, steam railway locomotives, ships, and electricity generation.

These uses are now largely obsolete, in favour of oil or gas. because oil and gas are easier to handle.

Today coal's use is mainly in the reduction of iron ore to produce iron.

Coal if heated in coke ovens to form impure carbon which is the carbon used for iron ore reduction.

In being heated in coke ovens it also releases other materials, notably, carbon dioxide, amminia, sulphur dioxide, hydrogen sulphide. etc., All these materials can be collected and used in the manufacture of other chemicals.

Coal can be thought of as 'solid crude oil'. Reason, it can by an industrial process, be converted into oil and gas. This industrial process, named SASOL, was developed in South Africa, during the 1960's, when there was a trade embargo of importing crude oil into South Africa, due to Apartheid'.

South Africa is 'blessed' with large deposits of coal, but no crude oil.

Combusting coal leaves a lot of dust/carbon particles and black smoke, and carbon dioxide. compared to oil /gas which also leaves a lot of carbon dioxide. The storage of coal , because it is a broken rock leaves a lot of unused space. As a solid material it is more difficult to transport, train/road, than oil/gas by pipeline.

So in the modern world, coal is mainly used in regions where it is plentiful , for iron ore reduction and electricity generation.

Today, the main use of coal in the United States is related to electricity generation and industry.

Coal can be converted to oil .

The South African's during the years of Apartheid, when they suffered a trade embargo on oil, developed the industrial process of converting coal to oil, viz. SASOL.

South Africa has millions of tons of coal that can be mined.

A coal seam can be used as a key bed in geology to help determine the relative age of surrounding rock layers through the principle of superposition. Key beds are distinctive, widespread, and easily recognizable rock layers that can be correlated across different locations. By identifying a coal seam as a key bed, geologists can use it as a reference point to establish the relative ages of other rock layers in the area. This can help in understanding the geological history and sequence of events in a particular region.

Depends on what you want to do with them.

Coal can be heated in coke ovens to liberate various gases that can be used industrially. e.g. sulphur dioxide, methane etx, thre solid product is coke and impure form oc carbon, which can be used for heating.

Charcoal is baked wood. again an impure form of carbon, and was used , historically, to smelt metal ores to release the metals. Artistically, it is a very good material for charcoal sketching, or 'ground dimensions for oil painting.

Burning coals release heat.

The heat is used to voil water to mke st4eam under pressure.

This pressurised steam drives a turbine, which in turn roates a magnet in a coil to produce electricity.

So over all it is thermasl energy changing into electrical energy.

Oh, dude, that's a wild one! So, technically, the first reported finding of coal near the South Pole was by a British expedition led by Ernest Shackleton in 1909. Like, they were probably just strolling around, looking for penguins or something, and stumbled upon some coal beds. Can you imagine finding coal in such a chilly spot? Like, talk about a hidden gem!

Canada and the USA are the most extreme countries, but Asia and Africa are where they are found and we must perpose that those are the countries that have the most coal and oil. by:BREANA FULLERTON

Oh, let's talk about the beauty of nature instead! Tar is found in various products like asphalt for roads and roofs, as well as some skincare products like coal tar shampoo for certain skin conditions. Remember, there's always beauty to be found in the world around us, even in unexpected places.

Coal is to scuttle as something is to caddy. In this analogy, the relationship between coal and scuttle is that coal is typically stored or carried in a scuttle. Similarly, in the second part of the analogy, something is typically stored or carried in a caddy. A caddy is a container or holder used to store or transport items, such as tea in a tea caddy or golf clubs in a golf caddy.

Yes, coal dust burns faster than a single lump of coal because it has more surface area exposed to oxygen, allowing for quicker combustion. This increased surface area allows for more efficient burning and a faster release of energy.

They ate a lot of beans and pork because those kept well and little else. They had flour and sourdough to make bread and biscuits and flapjacks. They had coffee. They had game. Everything else was in fairly short supply and was sold at highly inflated prices because of the amount of gold in circulation in the camps and in the city.
