Is forming a bar of gold into wire a chemical change or a physical change?
Forming a bar of gold into wire is considered a physical change. This is because the gold's chemical composition remains the same during the process, only its physical shape is altered.
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 forming a bar of gold into wire a physical change or a chemical change?
Still a physical change because its still gold and weren't doing anything like making a new element or mixing chemicals with the gold. So its still a physical change.
Is the glowing of a platinum wire in a flame a physical or chemical change?
It is a physical change. A physical change involves changing a substance only in its appearance, smell, taste, feel, or sound. A chemical change involves changing what makes up the substance or the way the substance reacts with other substances. When a normal platinum wire is placed over a flame, it glows. This is a physical change because the things that make up the platinum have not been changed, but the appearance has changed.
Forming a bar of gold into wire chemical or physical?
When a gold bar is shaped into a wire, the gold's chemical properties do not change. Only the physical appearance changes when gold is changed in shape. Thus, this is an example of a physical change.
Is the tranishing of silver chemical or physical change?
Drawing it into a wire is a physical change of silver.
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 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 twisting a wire chemical or physical change explain?
It is physical. The wire changes shape, but it is still made of the same materials.
Is bending a metal wire a physical or chemical change?
It's a physical change, because bending a wire doesn't affect the chemical makeup of it.
Is a bending a metal wire a physical change?
It's a physical change, because bending a wire doesn't affect the chemical makeup of it.
Is forming a bar of gold into wire a chemical change or a physical change?

Is bubbles when aluminuim wire is dropped into HCL a physical change?
No. The aluminum is reacting with the acid; it is a chemical change.
Is the color of iron wire a physical or chemical change?
The color change of iron wire when it rusts is a chemical change because it involves a reaction with oxygen in the air to form iron oxide. This new substance has different properties than the original iron.
Is cooper wire a mixture?
No, copper wire is not a mixture; it is a pure substance made primarily of copper metal. Copper has distinct physical and chemical properties, and when drawn into wire, it retains its metallic characteristics. Any impurities present in the wire would be minimal and would not classify it as a mixture.
Is forming a bar of gold into wire a physical change or a chemical change?
Still a physical change because its still gold and weren't doing anything like making a new element or mixing chemicals with the gold. So its still a physical change.
