∙ 12y agothis 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.

Is breaking glass chemical or physical?
Breaking glass is a physical change, as it does not change the chemical composition of the material.
When glass brakes is it a physical change?
A glass breaking is a physical change because the chemical composition of the glass does not change.
Is breaking glass is a physical or chemical change?
Purely physical.
Is glass breaking a chemical or physical change and why?
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.
Why is breaking a glass a phyiscal change?
Breaking glass is a physical change because there is NO chemical difference ... from before to after.
Is breaking a glass beaker chemical or physical?
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.
Is breaking of glass physical or chemical change?
It is a physical change. The resulting fragments of glass are still glass and of the same composition.
Is a glass breaking a chemical change?
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.
Is breaking glass a chemical property?
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
How can breaking a glass jar be a physical change?
Breaking a glass jar changes the physical form of the glass without changing its chemical composition.
Is breaking glass a physical change and why?
It is a physical change because the chemical composition remain unchanged.
Is breaking glass a physical change?
Yes, as it's still glass. There is no chemical/molecular change.
