why tearing of paper , cutting of cloth is physical change why please give me the answer in detail and fast.
Dear student,
Tearing of paper and cutting of cloth is a physical change because the physical properties are changed (Volume and size) but the material of a teared paper and cutting of cloth is the same only shape and size are changed and it is not important that every irreversible change is a chemical change. Physical change is usually reversible but not always.
Conclusion-
No new substance is formed
Only shape and size has changed
The material is same.
Hence it cannot be a chemical change.
