Coal (fuel source)
Coal has been the primary fossil fuel since Native American times. Once coal companies started in the United States in the early to mid 1800s, men from England (Great Britain now United Kingdom), Scotland, and other European countries were recruited to come to the US. Local coal miners, especially in the bituminous coal field (Pittsburgh PA Coal Field which extended through SW PA, West Virginia, Ohio, Indiana, Kentucky) viewed these immigrants as "foreigners" and demanded companies only hire "practical" (experienced) miners; however, this idea formed solely because of language barriers and other biases, since overseas miners were very experienced in their home countries. Coal, as a fossil fuel, has been continuously mined in the US from the mid-1800s to the present.

When we burn a log a lump of coal or gasoline what is really happening from an energy stand point?
When a log, lump of coal, or gasoline is burned, chemical energy stored in the molecules is converted to heat and light energy through a process called combustion. This release of energy is a result of the bonds in the molecules breaking and forming new bonds with oxygen in the air. The heat and light produced during this process can be harnessed for various applications.
Yes, coal can contain trace amounts of mercury. When coal is burned, mercury can be released into the air and subsequently contaminate water sources. Efforts to reduce mercury emissions from coal-fired power plants include the use of pollution control technologies.
Pockets formed by the coals in a coal fire seem brighter than the coals themselves?
Even though the temperature of coal and pockets formed by them is same still we observe that pockets seem to be brighter than coal because they form the cavity and act as a black body so radiations emitted by them are highest intensity.
What is the highest quality of coal called?
The highest quality of coal is called anthracite. Anthracite is known for its high carbon content, low moisture content, and high energy density, making it a premium grade of coal for heating and industrial use.
Why must china import petroleum natural gas and coal?
China imports petroleum, natural gas, and coal because its domestic production is not sufficient to meet its huge demand for energy. Rapid industrialization and urbanization have led to a significant increase in energy consumption, prompting China to rely on imports to fulfill its energy needs.
Why is coal not considered biomass?
Coal is not considered biomass because coal is a non-renewable fossil fuel formed from the remains of ancient plants and animals that have been subjected to intense heat and pressure over millions of years. Biomass, on the other hand, refers to organic matter derived from plants or animals that is renewable and can be replenished relatively quickly.
Why is the petroleum called fossil fuel?
Petroleum is called a fossil fuel because it is formed from the remains of ancient plants and animals that have been buried and transformed under high pressure and heat over millions of years. This process created the hydrocarbons found in petroleum, making it a non-renewable resource.
Do coal produce more energy than wood?
Yes, coal produces more energy than wood when burned. Coal is more carbon-dense and has a higher energy content compared to wood. This is why coal has been traditionally favored as a fuel source for power generation and industrial processes.
What is the last effect of burning sulfur coal?
The last effect of burning sulfur coal is the release of sulfur dioxide into the atmosphere. Sulfur dioxide is a major air pollutant that can contribute to acid rain, smog, and respiratory issues in humans. It also plays a role in the formation of fine particulate matter, which can have negative impacts on both human health and the environment.
What type of coal is used to make coke?
Metallurgical coal, also known as coking coal, is used to make coke. This type of coal has high carbon content and low impurities, making it suitable for the production of coke, which is used in the steelmaking process.
Why does some coal have very little sulfur in it?
Coal with very little sulfur content is known as low sulfur coal. This type of coal forms in environments where conditions limit sulfur availability during its formation, such as in freshwater swamps or peat bogs. Lower sulfur content in coal is desirable because sulfur emissions contribute to air pollution and acid rain when coal is burned for energy.
Coal is used in homes for heating and cooking. It is burned in stoves or furnaces to generate heat. Coal can also be used in fireplaces and as a backup source of energy during power outages.
Why is coal the prefered choice for electricity?
Coal has been a preferred choice for electricity generation due to its widespread availability, energy density, and low cost compared to other fossil fuels. However, it is falling out of favor due to its high carbon emissions and negative impact on the environment and human health. Countries are transitioning to cleaner and more sustainable sources of energy to reduce carbon emissions and combat climate change.
What element in coal is oxidised to form this gas?
Carbon in coal is oxidized to form carbon dioxide gas when coal is burned.
The sun does not have a direct effect on coal. Coal is formed from ancient plant material that underwent millions of years of geological processes like heat and pressure to become a fossil fuel.
How much does a load of coal weigh?
The weight of a load of coal will depend on the amount of coal that you ordered in the load.
Which substances is obtained by heating coal in absence of air?
When coal is heated in the absence of air, it undergoes a process called destructive distillation or pyrolysis, resulting in the formation of substances such as coal gas, coal tar, and coke.
What black powder is released when you burn coal?
Soot or carbon black is released when coal is burned. It is a fine powder composed primarily of carbon particles that form during incomplete combustion.
The countries that produce & export the most coal is:
1.China
2.USA
3.European Union
4.India
6.Russia
9.Germany
10.Poland
Yes, coal is commonly used as a fuel for fires due to its high energy content and ability to burn for a long time. It is often used in fireplaces, stoves, and for heating purposes.
To use less coal, we can invest in renewable energy sources such as solar, wind, and hydropower. Implementing energy efficiency measures and promoting the adoption of electric vehicles can also help reduce the overall demand for coal-generated power. Additionally, setting policies and regulations that incentivize businesses and industries to reduce their reliance on coal can further drive the transition to cleaner energy alternatives.
Why is the heat content of coal important in determining how the coal is used?
The heat content of coal, measured in British thermal units (BTU) per pound, determines how much energy the coal can produce when burned. This is important in determining the efficiency and cost-effectiveness of using coal as a fuel source. Higher heat content coal can produce more energy per pound, making it more desirable for power generation and other industrial applications.
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.
