- What is the process of extracting metal from its ore called?
- Smelting
- Refining
- Casting
- Electrolysis
The correct answer is Smelting.
Smelting is the process of heating ores to extract metals from their natural states, often combining them with other elements to form alloys. - What metal alloy is made from copper and tin?
- Pewter
- Steel
- Brass
- Bronze
The correct answer is Bronze.
Bronze is an alloy made primarily of copper and tin, and it is known for its strength and durability. It was widely used during the Bronze Age for making tools, weapons, and sculptures. - Which metal is the most abundant in the Earth’s crust?
- Copper
- Silver
- Iron
- Aluminum
The correct answer is Aluminum.
Aluminum is the most abundant metal in the Earth’s crust, making up about 8% of its composition. It is lightweight, corrosion-resistant, and an excellent conductor of electricity. - Which metal is the primary component of steel?
- Manganese
- Carbon
- Chromium
- Iron
The correct answer is Iron.
Steel is an alloy primarily composed of iron, with small amounts of carbon and other elements added to improve its properties, such as strength, ductility, and corrosion resistance.
- Which metal is the best conductor of electricity?
- Silver
- Copper
- Aluminum
- Gold
The correct answer is Silver.
Silver is the best conductor of electricity, followed closely by copper and gold. However, due to its high cost, silver is not commonly used for electrical applications. - What type of steel contains at least 10.5% chromium?
- Tool Steel
- Alloy Steel
- Carbon Steel
- Stainless Steel
The correct answer is Stainless Steel.
Stainless steel is an alloy that contains at least 10.5% chromium, which gives it its corrosion-resistant properties. - What is the process of heating and cooling a metal to improve its mechanical properties called?
- Heat Treatment
- Quenching
- Tempering
- Annealing
The correct answer is Heat Treatment.
Heat treatment is the process of heating and cooling a metal to change its microstructure and improve its mechanical properties, such as strength, hardness, and ductility. - Which metal is liquid at room temperature?
- Tin
- Gallium
- Mercury
- Lead
The correct answer is Mercury.
Mercury is the only metal that is liquid at room temperature, with a melting point of -38.83°C (-37.89°F) and a boiling point of 356.73°C (674.11°F). - What is the process of removing impurities from a metal by melting it and then allowing it to solidify called?
- Refining
- Smelting
- Casting
- Forging
The correct answer is Refining.
Refining is the process of removing impurities from a metal by melting it and then allowing it to solidify, often by pouring it into a mold. - Which metal is primarily used to galvanize steel?
- Tin
- Copper
- Zinc
- Lead
The correct answer is Zinc.
Zinc is primarily used to galvanize steel, a process that involves coating the steel with a thin layer of zinc to protect it from corrosion.

- What element is added to steel to improve its resistance to corrosion and staining?
- Nickel
- Manganese
- Carbon
- Chromium
The correct answer is Chromium.
Chromium is added to steel to improve its resistance to corrosion and staining, forming a thin, invisible layer of chromium oxide on the surface that protects the underlying metal. - Which metal is known for its green patina when exposed to the elements?
- Copper
- Brass
- Bronze
- Iron
The correct answer is Copper.
Copper is known for developing a green patina when exposed to the elements, a result of the metal reacting with oxygen and other substances in the atmosphere. - What is the process of shaping metal by hammering, bending, or pressing it called?
- Rolling
- Extrusion
- Forging
- Casting
The correct answer is Forging.
Forging is the process of shaping metal by hammering, bending, or pressing it, often while it is heated to make it more malleable. - Which metal is commonly used to make electrical wiring due to its high conductivity and ductility?
- Iron
- Silver
- Aluminum
- Copper
The correct answer is Copper.
Copper is commonly used to make electrical wiring because of its high conductivity and ductility, which allows it to be easily drawn into thin wires.
- What is the name of the process in which a metal is coated with a thin layer of another metal to improve its appearance or protect it from corrosion?
- Anodizing
- Galvanizing
- Painting
- Plating
The correct answer is Plating.
Plating is the process of coating a metal with a thin layer of another metal, typically using electrolysis, to improve its appearance or protect it from corrosion.
