Final answer:
Copper wire is a mixture composed of copper and other elements that are physically combined.
Step-by-step explanation:
Copper wire is a mixture of copper metal and other elements. An element is made up of only one type of atom, whereas a compound is made up of two or more different types of atoms combined together in a fixed ratio. On the other hand, a mixture is made up of two or more substances that are physically combined and can be separated by physical means.
In the case of copper wire, it consists of copper atoms along with other elements like tin or nickel depending on the specific type of wire. These elements are mixed together to enhance the properties of the wire.
So, in summary, copper wire is a mixture, as it is composed of copper and other elements that are physically combined.
