Grinding chalk to chalk dust is a physical change because the texture and size may change but the its molecules are still the same.

An example of chemical change is burning paper because ash is chemically different from paper.

Is a chalk grinding a physical change?

It doesn't matter if something is reversible or irreversible. it will not depend if it is a chemical or physical change. A physical change is when the composition of a substance remains unaltered (the particles stay the same) and no new substance is produced. Such as when you make a paper plane out of paper, the appearance changed, the particles stayed the same, no new substance was created, and the paper remains paper. A chemical change is when the composition of a substance is altered and a new substance is produced. Such as when paper is burned, the new substance produced is the carbon and other gases from the fire, and the composition of the paper changes, slowly disappearing.It usually is unless you draw so rapidly that the heat of the friction heats the paper and causes it to smoke.


What kind change is grinding chalk into powder?
