Breaking, grinding, cracking are all examples of a physical change. The nature of the substance has not changed, just the size of the pieces has changed.
It iss a physical change because you are not changing the chemical composition of the beaker.
Breaking glass is a physical change.
It is a physical change.

Yes, as it's still glass. There is no chemical/molecular change.
A physical change can be reversed, for it does not change what the object is made of. The glass, even when broken, is still glass. It can be put back into its original state (possibly through melting) because it never changed what it was made out of.
Breaking, grinding, cracking are all examples of a physical change. The nature of the substance has not changed, just the size of the pieces has changed.
that depends. changing the shape of glass is physical but if its a glass that can be effected by heat then if can be chemical. i would say its both.
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.

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
Purely physical.
Physical change because before and after breaking a glass, the glass is still SiO2 (Silicon): it's chemical makeup is not changed by the breakage.
Breaking a glass jar changes the physical form of the glass without changing its chemical composition.
Breaking glass is a physical change because there is NO chemical difference ... from before to after.
A glass breaking is a physical change because the chemical composition of the glass does not change.
It is a physical change. The resulting fragments of glass are still glass and of the same composition.
It is a physical change because the chemical composition remain unchanged.
A chemical change is when the molecules of an object / solution are changed. A physical change is when the object / solution is altered without molecular change. Breaking glass is a physical change.
Yes, as it's still glass. There is no chemical/molecular change.
