It is a physical change because it has not changed its chemical composition.
Copper sulfate is a substance, not a change. It can undergo physical and chemical changes.
If you meant to ask, "Is stretching copper into wire a physical or chemical change", it's a physical change.
Physical change
It can be. Temperature increases usually induce physical changes in the broad sense. If the change in temperature merely induces a state change (for instance, the copper is melted - becoming a liquid) then it is purely a physical change. Presuming that heating will occur in the presence of air, it will also increase the rate of oxidation and, therefore, be indirectly inducing a chemical change.
it is a chemical change Sodium carbonate + Copper sulfate react to make Sodium sulfate + Copper carbonate
This is a physical change.

Physical change
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).
Yes, but not a chemical change.
