Question

What kind of change is shown by tearing of paper?

Answer 1

Changes in Process

1. Any change that occurs during a process can be classified into two categories: physical change and chemical change.
2. Physical change is described as a change in the physical properties of the object under the observer's inspection. It signifies that the thing under observation is not undergoing any chemical changes. The matter's form may change, but its chemical content remains unchanged. Melting wax is an example.
3. Chemical change, on the other hand, refers to changes in the chemical content of the objecting. As a result, a chemical reaction is occurring in this situation. Burning magnesium ribbon is an example of its.
4. 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.
