Physical properties of coal include its carbon content, which typically ranges from 45% to 86%, and its calorific value, which indicates the energy released upon combustion. Coal's appearance can vary from dull black to shiny, depending on its type, with common forms including anthracite, bituminous, sub-bituminous, and lignite. Other notable properties include its hardness, specific gravity, and porosity, which affect its combustibility and usability in various applications. Additionally, coal may contain impurities such as sulfur and ash, which influence its environmental impact when burned.

When do the physical and chemical properties change?
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
Is coal dust chemical or a physical toxicant?
Coal dust is considered a physical toxicant because it can cause harm through its physical properties, such as being inhaled and causing respiratory issues or skin irritation. Chemical toxicants, on the other hand, refer to substances that cause harm due to their chemical properties or composition.
Coal is coal and diamond is diamond but coal is not a diamond?
Correct.Although they are based on the same element (carbon) they have vastly different structures and atomic arrangements, resulting in very different physical and chemical properties. Such forms are known chemically as allotropes.
Physical properties of coal and snow?
Coal is a black, carbon-rich sedimentary rock that is combustible and used as a fuel source. It is hard, brittle, and has a black or dark brown appearance. Snow is a precipitation in the form of ice crystals that fall from clouds. It is white, soft, and composed of frozen water molecules. Snow is light and can vary in density depending on the temperature and moisture content.

Is breaking coal into pieces chemical or physical change?
Breaking coal into pieces is a physical change because it does not alter the chemical composition of the coal. The coal remains composed of the same elements before and after being broken into pieces.

How would you describe the physical properties of coal?
Coal is a black, combustible sedimentary rock that is mainly composed of carbon. It is brittle, typically black or brown in color, and has a wide range of heating values depending on the type of coal. Coal can leave a powdery residue when handled and may have a distinct odor when burned.
Is mining coal a physical or chemical change?
Mining coal is a physical change because the act of extracting coal from the earth does not alter its chemical composition. The coal remains chemically the same before and after the mining process.

How is an chemical change differs from a physical change?
Physical change is the change in which only physical properties changes ,like color, hardness, density etc. Chemical changes affect the composition as well as chemical properties of matter and result in formation of new substance. Examples of chemical changes are : Burning of coal Burning of Paper Electrolysis of water
Can coal change into a diamond?
Yes, coal can change into a diamond through a process called metamorphism, which involves high pressure and high temperature deep within the Earth's crust. Both coal and diamond are made of carbon atoms, but the arrangement of the atoms is different, resulting in the difference in their physical properties.
