Positive effects of using coal include its abundance, reliability for power generation, and affordability compared to other energy sources. Coal also supports jobs in the mining and energy sector.
The bulk density of coking coal typically ranges from 0.8 to 1.5 grams per cubic centimeter, depending on the coal's composition and particle size. This parameter is important for determining the handling and storage requirements of the coal, as it affects transportation costs and storage capacity. Testing is usually done using standard procedures to accurately measure the bulk density.
A man who hews coal is typically called a "coal miner." This individual is responsible for extracting coal from underground mines using specialized tools and equipment.
To find the density of a piece of coal, you would first measure the mass of the coal using a scale. Next, you would measure the volume of the coal using displacement method or a caliper. Finally, divide the mass of the coal by its volume to calculate the density, which is typically expressed in g/cm³ or kg/m³.
Coal reserves refer to the quantity of coal that can be technically and economically extracted from a coal deposit using current mining methods. It represents the economically recoverable portion of coal resources. Coal reserves play a vital role in energy security and future energy planning.
Some ideas to represent coal for a school project include using black construction paper cutouts or drawings, using black rocks or charcoal pieces, creating a miniature coal mine diorama, or using black sand or soil as a substitute.

Coal has limited positive effects on the environment. It can provide reliable energy generation, support job creation in mining communities, and contribute to economic growth in some regions. However, these benefits are outweighed by the environmental impacts of coal combustion, such as air and water pollution, greenhouse gas emissions, and land degradation.
None.
Coal mining affects the economy because it is a relatively cheap energy resource, because it is abundant in most of America.
The negative affects are nausea, vomiting and hair loss. The positive affects such as chemo therapy, which decreases or stops the cancer cells.
it affects the environment because there might still be animals on the farm
