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, its a phyical 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
It is not that difficult if you know the difference between a chemical and physical change. A physical change is reversible and a chemical change is not. In a physical change a new substance is not formed. The breaking of glass is not reversible and is physical.
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.)
Since in breaking down there is no chemical change it's a physical change
Breaking glass is a physical change, as it does not change the chemical composition of the material.
Breaking glass is a physical change because there is NO chemical difference ... from before to after.
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.
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
A glass breaking is a physical change because the chemical composition of the glass does not change.
Purely physical.
Yes, as it's still glass. There is no chemical/molecular change.
It is a physical change. The resulting fragments of glass are still glass and of the same composition.
Breaking a glass jar changes the physical form of the glass without changing its chemical composition.
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 chemical change. It keeps its same chemical composition and is in a reversible state. You can remelt it and once again, make glass.
It is a physical change because the chemical composition remain unchanged.
