Coal (fuel source)

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 because it is a distinctive layer that is widespread and easily recognizable in the rock record. Key beds are used as markers for correlating and dating rock layers in different locations, and the distinct composition and boundaries of a coal seam make it a useful reference point for stratigraphic analysis and interpreting geological history.

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.

Alternatives to using coal include renewable energy sources such as solar, wind, and hydropower, which produce electricity without emitting greenhouse gases. Natural gas is often considered a transitional alternative, as it burns cleaner than coal. Additionally, nuclear power offers a low-carbon option for large-scale energy production. Biomass and geothermal energy are also viable alternatives that can help reduce reliance on coal.

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.

YES!!!

It is a rock.

Like all rocks, it can be broken with the use of a hammer, chisel, pick axe, or dynamite.

chemical. A chemical change is a change where a substance is changed and a new substance is formed. in the case of coal when the solid carbon in the coal combines with the oxygen in the air carbon dioxide (CO2) is formed.

Coal is an example of a non-renewable resource (NRR). Non-renewable resources are natural resources that cannot be replenished at the same rate they are consumed. Coal is formed from the remains of plants and trees that lived millions of years ago and takes a significant amount of time to regenerate. Once coal is extracted and burned for energy, it cannot be easily replaced.

it has led to humans having a greater effect on the environment.

There are several forms of coal.

Going from softest to hardest.

Peat, Lignite, Coal, and Anthracite.

'Peat' is just like a soft dirty black earth,but it is coal in geoloicial formation.

Lignite is a soft black rock that can easily be broken.

Coal ; is a hard shiny black rock, that needs an axe or pick to break it.

Anthacite ' is a very hard shiny black coal, and does not break easily to an axe/pick.

They are all carboniferous and will burn with increasing degree of heat and decreasing emission of smoke.

Yes, burning coal releases energy in the form of heat when its carbon content reacts with oxygen in the air to produce carbon dioxide and water vapor. This heat energy can be harnessed to generate electricity in power plants. However, burning coal also releases harmful pollutants and greenhouse gases into the atmosphere.

By Combustion (burning)

Coal is a black shiny carboniferous rock. If heated to 'red' heat' it will combust, releasing carbon dioxide, and other gases in the process. The product of burning is commonly called ash, but when combusted under controlled conditions it makes 'coke' ( impure carbon).,

In order of soft to hard ;

Peat,

Lignite

Coal

Anthracene.

1. Coke (Impure Carbon)

2. Ammonia

3. Sulphur dioxide

4. Hydrogen Sulphide

5. Methane

The above five items come from baking coal in 'Coke Ovens'.

From

Ammonia we can make (6)Ammonium nitrate (fertiliser.

Sulphur Dioxide we can make (7)sulphuric /(8)sulphurous acids

Methane we can make (9) polymers an other organic products

Also combust methane ( 10) heat./ energy.

In a coal mine

coal dust , mixed with oxygen and methane is known as 'fire damp'.

Any flame or electric arc will ignite a flash explosion.

Miners often breed canaries (finch type birds), and occasionally take then down the mine. This is because the bird is very susceptible to poisonous gases and fire damp. It is likely to fall off its perch if poisonous gases are present, whereupon the bird is quickly removed to cleaner air , where it recovers.

Coal dust , coal particles are best kept under control by the use of a fine spray / mist. of water.

Spacecraft use solar cells to generate electricity because coal combustion requires oxygen, which is limited in space. Solar cells can convert sunlight directly into electricity without the need for oxygen, making them a more practical and reliable choice for spacecraft power generation.

It is extremely unlikely. Coal is derived from the carbon in organic matter, mostly plant material, that is buried deep underground. So far we have found no direct evidence that Mars ever supported life. If it did, that life was probably not present in large enough amounts to leave behind coal deposits.
