Purely physical.
this is one of those weird questions. normally, a physical change is something that can be undone, however broken glass is not easily put back together. this is not, however a chemical change because by heating the pieces, they can be melted back into a single piece. a similar example is breaking an ice-cube. to put an ice-cube back together, you could melt the pieces and put them in a container in a freezer until they become a single piece again.
if this were a chemical change, then the glass would not be able to be put back together no matter what you do. for example: you cannot un-bake a batch of cookies.
Physical. It hasn't changed the chemical composition (mostly silicon).
This would be a physical change.
Chemical
Breaking glass is a physical change, as it does not change the chemical composition of the material.
A glass breaking is a physical change because the chemical composition of the glass does not change.
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 glass is a physical change because there is NO chemical difference ... from before to after.
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 is a physical change. The resulting fragments of glass are still glass and of the same composition.
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.
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
Breaking a glass jar changes the physical form of the glass without changing its chemical composition.
It is a physical change because the chemical composition remain unchanged.
Yes, as it's still glass. There is no chemical/molecular change.
