Is stretching wire into copper a physical or chemical change?
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.
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 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.
Is the sentence true or false the fact that copper wire can be bent shows that some solids do not have a definite shape?
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.
What has the lowest resistance copper wire or iron wire?

Is stretching wire into copper a physical or chemical change?
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.
Is copper wire a chemical property?
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.
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.
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.
Copper can be drawn into a thin wire as a physical property or chemical property?
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.
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 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.
Is drawing cooper into wire a chemical change?
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.
1 Bending a copper wire is an example of what type of property?
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).
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.
What are 4 physical properties of copper wire?
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.
Why copper wire becomes stronger when bent?
It becomes weaker and breaks when bent many times.
