Shredding wood is only a physical change because the chemical composition is still the same. Even though the force of friction is involved the wood doesn't create and ash or smoking embers which is the chemical change of wood. Although some of the chemicals used to prevent un wanted damage to wood during manufactured shredding would add a chemical composition change to the wood unknowingly
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.
Shredding paper involves cutting it into smaller pieces, which alters its physical form without changing its chemical composition. Once paper is shredded, it cannot be reconstructed back into its original form, making it a non-reversible physical change.
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.
ANSWER:Its a physical change. If you burned it and it became ash, its a chemical change. Physical change means it made no change on a molecular level. Its still paper, just in two separate pieces.It is a physical change, as the chemical property of the paper remains unchanged.
An irreversible change is a transformation that once it occurs, cannot be undone or reversed to its original state. This could be a chemical reaction that produces new compounds or a physical change that alters the structure of a material in a way that is permanent. Examples include burning of a piece of paper, cooking an egg, or a rusting metal.
paper shredding
physical, you are only changing its appearance! :P
because it only changes its appearance
because it only changes its appearance
Physical... Chemically it's still cheese - but the shredding changes its appearance.

Yes - and no.... Physically it's still paper - but the information on it can no longer be read.

I have a feeling that this is for homework, but whatever. Crushing stone, sawing wood and shredding paper are all examples.
Cutting down a tree. shredding of paper as well as same of the irreversible change
