It used to be called papyrus in ancient Egypt that was yellow. Then it was transformed into paper, which was a tan colour. We see paper as white because it is bleached.
Ash and smoke.
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.
A phsical change is something that can be changed but cant be changed back. for example: you can crumple a piece of paper but it is still paper. A chemical change means it has been changed perminetly so for example: If you burn the paper its ashes not paper. it was ashes but youy cant change it back into paper. Hope this helps :)
