color
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.
coal carbonisation is the enrichment of coal properties. it is done by heating under absence of air

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
physical
a physical change
it is a physical toxicant
