Shattered glass is a physical change because the identity of the glass does not change.
It is a physical change. The resulting fragments of glass are still glass and of the same composition.
A glass breaking is a physical change because the chemical composition of the glass does not change.
Yes, scratching glass is a physical property because it is a change that can be observed without altering the chemical composition of the glass. It is a physical change that affects the appearance and surface structure of the glass.
No, this is a physical reaction because no matter has exchanged etc. Instead, the lattice structure of the glass has been broken- which is simply physical. (Not even that sophisticated a physical change, as glass has no lattice structure.)
Purely physical.
This is a physical change. There is nothing that changes the components of either the diamond or the glass when the diamond is used to scratch glass.
Breaking glass is a physical change, as it does not change the chemical composition of the material.

it is a physical it changes shape but its still glass
Blowing glass is a physical phenomenon, or 'property'.
