Why do we use metals in wires?
(Select all that apply.)
a. Metals are lustrous.
b. Metals are reactive.
c. Metals conduct electricity.
d. Metals are ductile.
I think its b and c
electrical conductivity is certainly good for a wire
so is being able to form into long skinny shapes (ductility)
Actually, the correct options are c and d.
We use metals in wires because:
c. Metals conduct electricity: Metals have a high electrical conductivity compared to other materials. This means that electric charges can move freely through the metal atoms, allowing electricity to flow easily through the wire.
d. Metals are ductile: Metals can be drawn into thin wires without breaking. This property, known as ductility, allows us to shape metals into long, thin wires that can be easily manipulated and connected to devices or electrical circuits.
It is important to note that option a, metals being lustrous, is not a reason why we use metals in wires. Option b, metals being reactive, is not applicable because metals used in electrical wires are specifically chosen for their low reactivity and ability to resist corrosion.
To determine why we use metals in wires, let's analyze the given options:
a. Metals are lustrous: While metals may exhibit luster, this characteristic is not relevant to their use in wires. Luster refers to the shininess or reflective quality of a material, which does not directly affect the wire's functionality.
b. Metals are reactive: This statement is incorrect. Metals, in general, are not highly reactive compared to nonmetals. Some metals, such as gold and platinum, are even considered to be chemically inert. Therefore, this statement is not a valid reason for using metals in wires.
c. Metals conduct electricity: This statement is true. One of the primary reasons for using metals in wires is their ability to conduct electricity. Metals have a high electrical conductivity due to the mobility of their electrons, which allows the flow of electric charge along the wire. As a result, metals are commonly used in electrical wiring to transport electricity efficiently.
d. Metals are ductile: This statement is also true. Ductility refers to a material's ability to be drawn into a long, thin wire without breaking. Metals generally have good ductility, which allows them to be easily formed into wires of varying thickness. This property makes metals suitable for wiring applications where flexibility and ease of shaping are desired.
Based on the explanations provided, the correct answers would be c (Metals conduct electricity) and d (Metals are ductile).
