yes it is physical change but how can it be rewanable thats my question
The change in the crushed can appearance was caused by a physical change. When the can is crushed, the arrangement of its particles is altered, but no new substances are formed.
Yes, crushing a piece of chalk is a physical change because the chalk is still composed of the same molecules before and after being crushed. The change in appearance is only due to the physical state of the substance.
Crushing chalk is a physical change, not a chemical change. Physical changes alter the form or appearance of a substance without changing its chemical composition. So, when chalk is crushed, it remains the same substance chemically but in a smaller form.
Well you can't put it back together after it's been crushed, so it's a chemical change!
The crushing of the can is a physical change because no new substances are formed. The can's shape and size are altered, but the material itself remains the same.
it is a physical change :-)

It is only a physical change.
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.
Nope. That is a physical change. a sugar cube that is crushed into powdered sugar is still sugar.

Yes, a crushed can has chemical properties. They are the same as those of the can before crushing. Crushing a can is a physical reaction and not a chemical one. For instance, if a soup can is made of steel, the steel can be chemically attacked by something like sulfuric acid. And this is true whether the can is crushed or not.

this queston is stupid

A can being crushed is definitely a physical change. Same properties, just a different shape!
