Automobiles and refrigerators use which mineral?

Automobiles and refrigerators use which mineral?

• A. Copper
• B. Aluminum
• C. Iron
• D. Lead

Answer: (B)

Aluminum is favored here because it combines light weight with good strength and resistance to corrosion. Cars use aluminum to reduce weight, improving fuel efficiency, and refrigerators use it for cabinets, heat exchangers, and components where a lighter, durable material is helpful. Copper has excellent electrical and thermal properties, but it’s heavier and not as cost-effective for bulk car bodies and appliance shells. Iron (steel) is strong but much heavier, which isn’t ideal for widespread use in both applications. Lead is mainly used in batteries rather than in the main structure of vehicles or refrigerators. So aluminum fits best for both automobiles and refrigerators.
