It is only a physical change.
it is a physical change :-)
Dissolving sodium carbonate in water is a physical change, not a chemical change. This is because the chemical composition of sodium carbonate remains the same before and after dissolving.
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.

No, crushing sodium carbonate does not produce a new chemical substance. Thus, crushing is an example of a physical change.
Adding calcium chloride to sodium carbonate would be a chemical change because it results in the formation of new substances (calcium carbonate and sodium chloride) with different chemical properties than the original reactants.

Nope. That is a physical change. a sugar cube that is crushed into powdered sugar is still sugar.
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.
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.
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.
A can being crushed is definitely a physical change. Same properties, just a different shape!
