Tearing of a paper is a physical change because when the paper is torn only the appearance of the paper is changed and no new substance is formed. Since this is a physical change this change can also be reversed. Burning of paper is a chemical change when paper is burnt the chemical composition of the paper is changed at the molecular level. Subsequently the paper is turned into ash this chemical change is am irreversible change. Hence compared burning of paper is a chemical change and tearing of paper is physical change.

→Tearing of paper is a physical change but it is not reversible . Why ?
=> So , when we tear a paper - there's no formation of new products . The properties remains the same . Hence it's a physical change.
=> Also , this physical change is not reversible . This is because once you've torn a paper , you can't bring it back to its original shape and size. Means , you can't reverse the change .
•°• The change is physical as well as irreversible !
