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.
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.
What physical properties could you use to tell the difference between coal and snow?
Well... Color and hardness. (Improved from, "well... one is white and one is balck, one is hard like a rock and one is soft and almost liquid," by Contributor.).
Is wood being softer than coal a physical property?
Yes, the hardness of a material is a physical property. Wood is softer than coal, meaning it has a lower hardness and can be easily scratched or dented compared to coal.

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.
Is the change of plants remains into coal a physical or a chemical change?
The change of plant remains into coal is a chemical change. This process, known as coalification, involves the chemical alteration of organic material under high temperature and pressure over millions of years, leading to the formation of coal with different properties.
What is another name for bituminous coal?
Bituminous coal, or soft coal
