Which statement correctly describes the conductivity of the specified material?(1 point)
Aluminum has a low conductivity.
Copper has low conductivity.
Gold has high conductivity.
Plastics have high conductivity.
Gold has high conductivity.
The statement that correctly describes the conductivity of the specified material is: "Gold has high conductivity."
To determine which statement correctly describes the conductivity of the specified material, we need to understand the properties of different materials. Conductivity refers to the ability of a material to conduct electricity or heat. Higher conductivity means a material allows the flow of electricity or heat more easily, while lower conductivity refers to a material's poorer ability to conduct. Let's assess each statement:
1. Aluminum has a low conductivity: This statement is incorrect. Aluminum is actually a good conductor of both electricity and heat. It is widely used in electrical wiring and various industrial applications because of its relatively high conductivity.
2. Copper has low conductivity: This statement is incorrect. Copper is an excellent conductor of both electricity and heat. It is commonly used in electrical wires, electrical components, and plumbing due to its high conductivity.
3. Gold has high conductivity: This statement is correct. Gold is a highly conductive material, both in terms of electricity and heat. Its excellent conductivity, along with its resistance to corrosion, makes it suitable for use in electronics, electrical contacts, and various industrial applications.
4. Plastics have high conductivity: This statement is incorrect. Plastics, or polymers, generally have poor conductivity. They are considered to be insulators rather than conductors, as they do not readily allow the flow of electricity or heat.
Therefore, the correct statement that accurately describes the conductivity of the specified material is: "Gold has high conductivity."
