Is stretching wire into copper a physical or chemical change?
If you meant to ask, "Is stretching copper into wire a physical or chemical change", it's a physical change.
What is the chemical name of copper wire?
Copper. The wire is made of elemntal copper not a chemical compound. (Note the copper used may sometimes be alloyed with another metal or occasionally be a solid solution of small amounts of oxide in the pure metal. This improves the durability and handling characteristics of the wire.)
What is the chemical formula for bare copper wire?
The chemical formula is Cu with small amount of CuO impurity.
Is the sentence true or false the fact that copper wire can be bent shows that some solids do not have a definite shape?
true

What are the difference between a substance's physical properties and its chemical properties?
Chemical properties involve reacting with another substance. IE: burning of magnesium requires oxygen after which it is no longer magnesium. Physical properties do not. IE: metals are malleable, some very malleable, like copper wire can be bent with your hand. BUT it is still copper wire.
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
Copper can be drawn into a thin wire as a physical property or chemical property?
it is a physical property
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 are 4 physical properties of copper wire?
The same chemical properties as for any form of copper.
Is drawing copper into wire a physical property or a physical change?
Yes, it is. You aren't altering the chemical composition at all - it's still copper - you are merely changing its shape.
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.
Why copper wire becomes stronger when bent?
It becomes weaker and breaks when bent many times.
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.
