The roughness of a surface is a physical property. It refers to the texture and irregularities of the surface at a macroscopic level, which can be observed and measured without changing the substance's chemical composition. Therefore, roughness is determined through physical means rather than chemical reactions.
Coarseness is a characteristic, not a change.
If you burn something it is a chemical change, however if you melt of boil it, it is a physical change.
