Shredding paper is a physical change because it does not alter the chemical composition of the paper. The paper is simply being physically broken down into smaller pieces, but it is still made up of the same materials it was before shredding.
Coloring on a white piece of paper is a physical change because the color change is reversible and does not alter the chemical composition of the paper. The paper remains paper even after coloring on it.
Shredding paper involves changing the physical appearance and form of the paper without altering its chemical composition. The paper is simply being torn into smaller pieces, making it a physical change rather than a chemical one.
Soggy paper is a physical change because the composition of the paper remains the same - it is still paper even when wet. The change in state from dry to wet is reversible through drying, without any new substances being formed.
When paper is put in water, it undergoes a physical change. The paper fibers absorb water and swell, causing the paper to change in texture and appearance. This change is reversible, as the paper will return to its original state once dried.
paper shredding
physical, you are only changing its appearance! :P
because it only changes its appearance
because it only changes its appearance

Yes, shredding a piece of paper is a physical change. This is because the paper is being physically broken down into smaller pieces, but its chemical composition remains the same.
Not all physical changes are reversible because most times when such changes occur parts of the substance is lost to the environment.

Shredding paper is a physical change because you can put all the pieces of paper back together again, i.e. it is still paper. The chemical nature has not changed, only the APPEARANCE has changed.
That is a chemical change. Physical changes can be undone. Burning a bit of paper is another non-reversible change.
