The identity of the glass has changed
C
The mass of the glass has changed.
D
The size of the glass has changed.
E
The density of the glass has changed.
Explanation
When the glass shatters, its shape and size change because one object becomes many smaller pieces. It is still glass, so its identity has not changed. Assuming no pieces are lost, the total mass and the material’s density also remain the same.
