Besides for rearranging the glass pieces, one is not actually changing the chemical formula of the glass. Much like grinding NaCl, the crystals get smaller but the chemical remains the same.
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.
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
It is a physical change. The resulting fragments of glass are still glass and of the same composition.
Breaking glass is a physical change because there is NO chemical difference ... from before to after.
Purely physical.
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 a glass jar changes the physical form of the glass without changing its chemical composition.
Physical change because the molecules have not changed to form a new substance.
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.
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.
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.)
