Coal (fuel source)

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.

Coal is a solid fossil fuel formed from decayed plants, while oil is a liquid fossil fuel made from decayed marine organisms, and natural gas is a gaseous fossil fuel formed in a similar way to oil but with different components. Each fuel has different energy densities, environmental impacts, and uses.

It does not have coal on it but it used to thousands of years ago.

Coal deposits near the South Pole formed when the continent of Antarctica was located much further north and had a temperate climate, allowing for the growth of lush forests and plants. Over time, these plant materials were buried and compressed, forming coal deposits that are now exposed near the South Pole due to plate tectonics and continental drift.

Yes, the energy stored in coal came from the sun.

Plants using an ingenious process called photosynthesis, use energy from the sun, to take carbon-dioxide from the air, use the carbon and release the oxygen back to the air.

After the plant is eaten or dies and is decomposed or burned (the net effect is the same) the oxygen again breaks the chemical bonds, releasing the energy from the sun and liberating the carbon-dioxide back to the air to become the next generation of plants.

Coal is carbon from the air and energy from the sun.

Coal was formed from plant matter that was covered by mud or silt and subjected to intense heat and pressure over millions of years. The sun is the source of energy for all plants, therefore all of the energy held in coal originated from the sun.

The burning coal beds can be seen in the state of Colorado, specifically in the town of Crested Butte. The fires have been burning underground for over a hundred years and can sometimes be visible through fissures in the ground.

Dogs may try to eat coal due to a condition called pica, where animals consume non-food items. This behavior can be caused by nutritional deficiencies, boredom, or stress. Eating coal can be dangerous for dogs as it can lead to digestive issues or blockages. It is important to address the underlying cause and prevent access to coal to keep your dog safe.

Plants use the energy from the sun to make food. They depend on sunlight to power chemical reactions vital for life. In a number of instances, plants that lived long ago died, and their remains built up in a layer or layers. As more and more overburden was deposited on top of the layer, compression and time changed the "plant material" into coal. This gives rise to the idea that the fossil fuel coal contains energy from the sun.

Coal is often referred to as "buried sunshine" because it is formed from the remains of plants and organic materials that captured the energy of the sun through photosynthesis millions of years ago. This process transformed these organic materials into coal through heat and pressure over time, effectively capturing the energy of the sun in a concentrated form.

Coal is made from the decayed body parts of animals and plants so after a couple of days the particles from the plants and animals will start to be covered by leaves from trees and other things and for coal to be formed you must have heat and pressure and after a couple of years the decayed particles with the heat and pressure it will eventually form into coal and also plants get energy from the sun and animals get energy from the plants so that's how coal is related to the sun

Coal is composed of old plant material that was chemically altered over the course of millions of years. The coal contains energy from sunlight that the plants captured and stored via photosynthesis.

The figure with eyes made of coal is commonly associated with mythological or folkloric characters, such as monsters or creatures from various cultures. The concept of coal for eyes is often used to portray a dark or sinister appearance.
