Blowing glass is a physical phenomenon, or 'property'.
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.
It is a physical change. The resulting fragments of glass are still glass and of the same composition.
Physical change because the molecules have not changed to form a new substance.
I assume you are talking about a solid shattering. This is a physical change. The reason it is not a chemical change is that say in glass for instance, the silicon dioxide molecules themselves do not change. It is just the shape that changes.

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.
This is a physical process.
No breaking glass is not a chemical reaction, which is what i think you mean. Breaking the glass does not alter the chemical makeup or properties of the glass. Instead breaking glass is a physical reaction because it does alter the size of the glass and its appearance

The property of rocks that can be determined by whether they scratch glass is their hardness. This is measured on the Mohs scale, which ranks minerals based on their ability to scratch one another. If a rock can scratch glass, it indicates that its hardness is greater than that of glass, which has a hardness of about 5.5 on the Mohs scale. Conversely, if it cannot scratch glass, it is likely to be softer than this standard.
A physical property of glass is its transparency, allowing light to pass through without scattering.
Breaking glass is a physical change, as it does not change the chemical composition of the material.

This is a chemical reaction (dito change).
Yes, exactly. If you ever do not know just remember that the basic chemical properties of glass and scratched glass are the same, so it's definitely a physical change. good job!
Purely physical.
