Yes. Crushing a rock is a physical change :)
Crushing an aluminum can is a physical change because the substance itself (aluminum) remains the same before and after crushing. The change in shape and size does not alter the chemical composition of the can.
The physical change of making foil into a ball involves shaping and compressing the foil. By rolling and compacting the foil into a ball shape, its appearance and form are altered without changing its chemical composition.
The density of the metal in the crushed can remains the same as the density of the metal before it was crushed. Density is an intrinsic property of a material that does not change with physical alterations like crushing. So, the density of the metal in the can will not change due to the crushing process.
1. breaking a rock in half 2. ripping a piece of paper
Change of state (melting freezing etc), change of shape (being molded into something), and basically anything that does not actually have the matter change, but the physical property (exceptions are odors colors etc). Hope this helps.
Crushing rocks is a physical property because it does not change the chemical composition of the rocks. It only alters their physical state or appearance.
Crushing a can would be a physical change. It would only change the shape.

Crushing a rock is a physical change. It is still rock, just in smaller bits.
Crushing an aspirin is a physical change because the small pieces are still chemically the same as the aspirin tablet.

Crushing a piece of chalk is only a physical change. Chemically, it is still chalk.
Crushing an aluminum can is a physical change because the substance itself (aluminum) remains the same before and after crushing. The change in shape and size does not alter the chemical composition of the can.
No. Crushing is a physical change.
Yes. Physical change is when you change the appearance but not the actual object. Crushing an aluminum can is a physical change because you have only changed its shape, but not its chemical composition.
Crushing a soda can is a physical change because the substance itself (aluminum) is not altered chemically. The can's shape changes, but its chemical composition remains the same.
Crushing creates a physical change in the size of the pieces but it does not change their chemical make up.
