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.
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.
A glass breaking is a physical change because the chemical composition of the glass does not change.
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.
