Wrapping is a physical process.
Yes
It is a physical process.
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.
No. It is a physical change.
Physical change
A physical change would be a change in a physical property. A "physical property", by itself, may or may not change.
Aluminum bending is a physical change. This is because the aluminum is still the same aluminum as it was before just in a different shape.
Physical. It's still aluminum foil.
Physical
It is a physical change because it can be reversed. All you have to do is weld the foil back together!
Physical. It's still aluminum foil.
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.
It's a chemical change. The aluminum foil is rusting, which cannot be undone, meaning that this is a chemical change, not a physical. Physical changes can be reversed.
It is a physical process.
yes
If the aluminum bubbles it will be a chemical change.
Crushing an aluminum can is a physical change because you have only changed its shape, but not its chemical composition.
When a aluminum can is crushed, it undergoes a physical change, because even though the object got crushed and misshaped it still has the same identity.The identity has never changed.
