Is crushing a can a physical change or a chemical change?

Crushing a can is a physical change because it only alters the shape and size of the can without changing its chemical composition. The metal of the can remains the same, and no new substances are formed. Crushing the can does not break any of the metal’s atomic bonds or molecules; it merely deforms the object. This change is reversible, as the can can potentially be reshaped back into its original form without changing the material itself. Therefore, crushing a can is classified as a physical change rather than a chemical one.
