Stretching wire into copper is a physical change because the composition of the material remains the same. The rearrangement of copper atoms in the wire does not alter the chemical identity of the substance.

A sheet of copper can be pounded into a bowl a physical or chemical change?
Pounding a sheet of copper into a bowl is a physical change because the copper is still the same substance before and after the change. The change in shape does not alter the chemical composition of the copper.
Is a piece of copper cut in half a physical or chemical change?
Cutting a piece of copper in half is a physical change because it only alters the physical appearance of the copper without changing its chemical composition.
Is copper sulphate a physical change or chemical?
Copper sulfate dissolving in water is a physical change as no new substance is formed. However, if copper sulfate is heated to decomposition, it would be a chemical change because a new substance is formed.
Is melting copper an example of chemical 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.
Is copper conducts electricity chemical or physical change?
Copper conducting electricity is a physical change because it involves the movement of electrons within the material, without changing its chemical composition.
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 a physical or chemical change?
its a physical change
A sheet of copper can be pounded into a bowl a physical or chemical change?
Pounding a sheet of copper into a bowl is a physical change because the copper is still the same substance before and after the change. The change in shape does not alter the chemical composition of the copper.
Is hammered copper a physical change?
Yes, hammered copper is a physical change. When copper is hammered, its shape and size change, but its chemical composition remains the same.
Is a piece of copper cut in half a physical or chemical change?
Cutting a piece of copper in half is a physical change because it only alters the physical appearance of the copper without changing its chemical composition.
Is copper in a Bunsen burner a physical or chemical change?
Using a Bunsen burner to heat copper is a physical change. The copper undergoes a change in its physical state from solid to liquid without changing its chemical composition.
The melting point of copper is 1083 C is this a chemical change or physical change?
The melting of copper is a physical change because it involves a change in the state of matter from solid to liquid without altering the chemical composition of copper itself.
Reaction of copper and heat is physical change or chemical change?
The reaction of copper with heat is a physical change because no new substances are formed. When copper is heated, it undergoes a change in state from solid to liquid without changing its chemical composition.
Is copper one pounded into sheets is a chemical or physical change?
This is a physical change.
Is a piece of copper is cut in half a physical or chemical change?
Physical change
Is piece of copper is cut in half a physical or a chemical change?
Physical change
Is copper sulphate a physical change or chemical?
Copper sulfate dissolving in water is a physical change as no new substance is formed. However, if copper sulfate is heated to decomposition, it would be a chemical change because a new substance is formed.
