Explanation: 

Detailed explanation-1: -When we tear a piece of paper, we can see that the chemical content remains the same; only one thing that’s changed is the size of the paper bits that form as we tear the paper further. Its physical state has changed. As a result, tearing a piece of paper is an irreversible physical change.

Detailed explanation-2: -The pieces of paper obtained have the same molecules as the original sheet of paper. Thus, tearing of a paper sheet is a not a chemical change, but it is a physical change.
