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.
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
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.)
A broken mirror is a physical change, not a chemical change. This is because the process of breaking a mirror alters its shape and structure but does not change its chemical composition. The glass remains glass, regardless of its fragmented state. Thus, the change is purely physical.
Breaking a glass. This is a physical change as the glass does not transform into a different substance. Chemical reactions involve the breaking and forming of chemical bonds to produce new substances.

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.
Glass breaking is a physical change because it does not involve a change in the chemical makeup of the glass. The bonds between the glass molecules are simply being rearranged when it breaks, but the composition of the glass remains the same.
Purely physical.
It is a physical change. The resulting fragments of glass are still glass and of the same composition.
Yes, as it's still glass. There is no chemical/molecular change.
Physical change because the molecules have not changed to form a new substance.
Breaking a glass jar changes the physical form of the glass without changing its chemical composition.
The breaking of a glass is a physical change because it involves the glass changing its shape and structure without undergoing a chemical reaction. The chemical composition of the glass remains the same before and after it breaks.
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.
