Water
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.
Coal is a solid, black or brownish-black substance, while snow is a soft, white, crystalline form of ice. Coal is combustible and used as a fossil fuel, whereas snow melts into water when heated.

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.

There is no antonym for coal. There usually are not antonyms for physical objects.
color
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.

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
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.
Snow is cold Chalk tastes bad.
