It is a physical change because you are changing the shape of the metal.
No such animal. That would be like hammering an orange into an apple.... They are both different pure elements. Unless you're handy with the nuclear fission or fusion, you cant make one from the other. No chemical or physical changes can alter that.
If you meant to ask, "Is stretching copper into wire a physical or chemical change", it's a physical change.
Chemical.
If it is just heated, the reaction is physical. If there is burning in the process, than the state of the copper will change, making it a chemical reaction.
Chemical change (which results in physical change).

Copper sulfate is a substance, not a change. It can undergo physical and chemical changes.
