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.
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.)
The chemical formula for bare copper wire is Cu, which represents the element copper. Copper is a highly conductive metal commonly used in electrical wiring due to its excellent conductivity properties.
False. The ability of copper wire to be bent does not necessarily indicate that some solids do not have a definite shape. Solids, including copper, have a definite shape but can still be flexible or malleable under certain conditions.
Copper wire has lower resistance compared to iron wire. This is because copper is a better conductor of electricity due to its higher electrical conductivity and lower resistivity.

No, copper wire is a physical property of copper. Chemical properties describe how a substance interacts with other substances to form new substances, while physical properties describe the characteristics of a substance without changing its chemical composition.
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.
If you meant to ask, "Is stretching copper into wire a physical or chemical change", it's a physical change.
The ability of copper to be drawn into a thin wire is a physical property, as it involves a change in its physical state without altering its chemical composition.
The color of a copper wire is a physical property. Physical properties can be observed or measured without changing the substance's chemical composition.
Forming a bar of copper into a wire is a physical change. The copper itself remains the same chemically, only its shape has been altered.
No, drawing copper into wire is a physical change because the chemical composition of copper remains the same throughout the process. The transformation involves only a change in shape and size, not in the chemical properties of the copper atoms.
It is a physical property. Malleability is a physical property in lots of metals (including copper). It is not a characteristic property, because it is not unique to copper. (Other metals share the same property).
Yes, it is. You aren't altering the chemical composition at all - it's still copper - you are merely changing its shape.
Conductivity: Copper wire is an excellent conductor of electricity. Ductility: Copper wire can be easily drawn into thin strands without breaking. Corrosion resistance: Copper wire is resistant to corrosion, which makes it a durable material for various applications. Malleability: Copper wire can be easily shaped and molded into different forms.
Cutting a copper wire is a physical change because the chemical composition of copper remains the same before and after cutting. No new substances are formed during the process, so it is considered a physical change.
