Is the color of a copper wire a physical property or chemical property?
Color is a physical property. However, change in color is a sign of a chemical reaction.
Is stretching copper into wire physical or chemical change?
If you meant to ask, "Is stretching copper into wire a physical or chemical change", it's a physical change.
Is copper wire a chemical property?
No. Copper (the metal, an element) has chemical properties. The shape of the copper (wire) does not affect it's chemical behavior.
Is this a physical or chemical change forming a bar of gold into wire?
copper
Is drawing cooper into wire a chemical change?
No. You start with copper, and when you are finished it is still copper, so there is no chemical change. It's a physical change. You changed the shape and moved some atoms around.

Is cutting a copper wire a chemical or physical change?
This is a physical change. Although you could say that the copper atoms are all moving around each other and changing which other atoms they are bonded to, you haven't reacted two substances to produce a different compound, so no chemical reaction. No reaction, ergo not a chemical change.
Is forming a bar of copper into a wire chemical or physical change?
Physical. It is simply changing the shape or configuration of solid copper to another shape. Chemical changes cannot be reversed.
What is the evidence that indicates that both physical and chemical changes occur when a copper wire is heated in a Bunsen burner flame?
When a copper wire is heated in a Bunsen burner flame, the copper's color changes to become a glowing red. It won't be restored to its original appearance after cooling. Instead, it becomes a black material called copper (II) oxide, which is 79.9% copper and 20.1% oxygen (was 100% copper before it was burned). This chemical change occurred as the oxygen in the air combined with the copper during the heating process.
