Coal (fuel source)

Approximately 60% of China's total energy supply comes from burning coal, making it the largest coal consumer and producer in the world. This heavy reliance on coal has raised environmental concerns due to the significant emissions of greenhouse gases and air pollutants associated with coal combustion.

It depends on the context in which they are being compared. Wood is a renewable resource and produces less pollution when burned compared to coal. However, coal generates more energy per unit of weight than wood.

Biomass is considered better than coal because it is renewable, meaning it can be replenished relatively quickly. Biomass also produces lower emissions of greenhouse gases when burned compared to coal, making it a cleaner source of energy. Additionally, biomass can be locally sourced, reducing transportation emissions and supporting local economies.

No, coal is not a good conductor of electricity. It is considered an insulator rather than a conductor, as it does not allow the flow of electric current easily. Metals such as copper and aluminum are better conductors of electricity.

Greenhouse gas emissions, such as carbon dioxide, are released from burning coal and contribute to climate change. These emissions are not considered useful in terms of energy production and instead have negative environmental impacts.

To create coal in alchemy, you can combine elements that represent darkness, such as carbon or lead, with elements that represent stability or earthiness, such as clay or rock. The process might involve heating and compressing the elements together in a controlled environment to simulate the conditions that naturally form coal over time. It's important to follow alchemical principles of correspondence and intention in order to create a successful coal-like substance.

The burning point of coal depends on the type of coal, but it generally ranges from 700°C to 1300°C. At these temperatures, coal combusts and releases heat energy.

Coal is formed from the remains of ancient plants that have been buried and exposed to high pressure and heat over millions of years. This process is known as coalification.

Coal can be used to produce electricity, heat in homes, and as a fuel for industrial processes. It can also be used to produce various chemicals such as tar, benzene, and ammonia. Additionally, coal is used in the production of steel and in the manufacturing of products like cement and paper.

Coal is a valuable energy resource as it is used for electricity generation, steel production, and other industrial processes. However, its value is diminishing due to environmental concerns, as coal combustion releases pollutants and greenhouse gases that contribute to air pollution and climate change. The declining cost of renewable energy sources is also impacting the value of coal as an energy source.

A coal bucket or coal hod is the term used for a container specifically designed for holding and transporting coal. These buckets are typically made of metal and have a handle for easy carrying.

Anthracite is so hard and pure that it is also referred to as "black diamond." It has a high carbon content and is considered the highest quality coal due to its low impurities and high energy density. Anthracite burns cleanly and efficiently, making it a popular choice for heating and industrial applications.

The primary pollutants from burning coal are sulfur dioxide (SO2), nitrogen oxides (NOx), particulate matter (PM), carbon monoxide (CO), and mercury. These pollutants can have harmful effects on both the environment and human health.

Coal has to be carefully burned to avoid releasing large amounts of waste gases, particularly sulfur compounds, that contribute to air pollution and acid rain. Oil is easier to burn cleanly, and natural gas is the least polluting of all fossil fuels.

There have been programs to produce cleaner solid, liquid, and gas fuels from coal, but few have been widely developed.

Anthracite coal has the most desirable burning properties and highest energy content among the different types of coal, due to its high carbon content and low moisture and impurity levels. It burns cleanly and efficiently, producing a high amount of heat energy.

Both diamonds and coal consist of carbon atoms.

Coal power plants typically produce around 2-3 kilowatt-hours (kWh) of electricity for every pound of coal burned. The energy produced can vary depending on the efficiency of the plant.

coal is not a mineral because it is an organic sedimentary rock formed from the remains of plants and animals, rather than being a naturally occurring inorganic solid with a specific chemical composition and crystal structure like minerals.

Rotting vegetation is overlaid by more rotting vegetation or other material.

This is compressed by the mass above and form peat.

Compression of the peat continues and form lignite (brown coal)

Compression continues on the lignite to form coal (clack shiny rock)

Compression may continue to form anthracite , the hardest form of coal .

NB with each compression watert/moisture is expelled, so coal and anthracite are very dry.

You are likely to be either coke (from coal) or carbon residue (from petrol). These solid substances are left behind when coal or petrol is heated in the absence of oxygen, which removes volatile components and leaves behind a carbon-rich material.

By digging big holes (called coal mines) in the ground and separating the coal, rock, and soil in the material dug from those holes.

Coal usually comes in layers (called seams) between layers of other sedimentary rocks.

The term you are looking for is "industrial emissions." These are pollutants released into the atmosphere during industrial processes such as refining petroleum, smelting metals, producing paper, and burning coal for power generation. Industrial emissions contribute to air pollution and can have harmful effects on human health and the environment.

There are approximately 6,700-8,300 BTUs per pound of lignite coal. A ton of lignite coal contains 20-24 million BTUs.

Coal is formed from dead plant matter that was buried and subjected to high pressure and heat over millions of years. This process transformed the plant material into coal through a process known as coalification.

Humans use coal primarily for electricity generation and heating. Coal is burned in power plants to produce steam, which drives turbines to generate electricity. It is also used in industrial processes such as steel production and cement manufacturing. Additionally, some homes and businesses use coal for heating purposes.
