its a physical change as it is reversible and no new substance is formed
Cutting bread is a mechanical or physical change, not a chemical change.
Cutting hair is a physical change because it does not alter the chemical composition of the hair. The cutting process only changes the physical appearance and length of the hair without changing its chemical structure.
That change would be physical, since the chemical identity of the wood has not been altered by cutting it.
Cutting doesn't change the chemical composition.
Cutting a circle out of a piece of paper is a physical change because the paper's chemical composition remains the same before and after the cutting. The change is only in the physical appearance and shape of the paper.
no,
No, it's a physical change. The material remains the same, it's just got a new shape.
No, cutting paper is a physical change, not a chemical change. The paper's chemical composition remains the same before and after cutting; only its physical shape is altered.

Cutting a piece of wood is a physical change because the chemical composition of the wood remains the same before and after cutting. The change is only in the physical appearance and shape of the wood.
It is a physical change because it is still a sheet of paper.
cutting your hair is probably a physical change I don't know
Cutting bread is a mechanical or physical change, not a chemical change.
It is not a chemical change because after cutting the chemical composition remain unchanged.
Cutting hair is a physical change because it does not alter the chemical composition of the hair. The cutting process only changes the physical appearance and length of the hair without changing its chemical structure.
