Are copper wires used for conducting wires in their physical properties?
Physical reaction, of course!The key to defining a chemical reaction or a physical reaction is whether or not a new substance is produced. A chemical reaction must produce a new substance, that is, the arrangement of the particles that make up the material changes. Copper wires use the conductivity of copper, whether copper or copper has been changed before or after conduction.
Yes, copper wires are used to make wires, using their physical propertiesElectrical conductivity (resistivity) is a physical property
Two reasons, first, the physical properties of the common substances, copper resistivity second only to gold and silverTwo is cheap, so in precision instruments, gold is often used as the key position of the connection
