Metals and Their Properties Quiz

What property of metals allows them to be hammered into shape?

• Ductility

• Malleability

• Sonorous

• Magnetism

Which of these metals is NOT typically magnetic?

• Iron

• Nickel

• Copper

• Cobalt

What characteristic is NOT associated with non-metals?

• Dull appearance

• High melting points

• Poor conductivity

• Brittle when solid

What is an alloy?

• A pure metal

• A mixture of metals or metals with non-metals

• A metal with a low melting point

• A naturally occurring metal

Why are alloys generally stronger than pure metals?

• They have higher melting points

• Their atomic arrangement is irregular, preventing atoms from sliding easily

• They are ductile and malleable

• They are magnetic

What property does bronze gain from being an alloy of copper and tin?

• Conductivity

• Hardness

• Magnetic properties

• Ductility

Why is steel a popular choice for making tools and machinery?

• It is magnetic

• It has a low melting point

• It combines strength with durability

• It is easy to shape

What separation technique involves heating a solution until the solvent evaporates?

• Filtration

• Condensation

• Distillation

• Evaporation

Which technique is used to separate a mixture by passing it through filter paper?

• Distillation

• Filtration

• Evaporation

• Crystallization

What is the purpose of a condenser in the distillation process?

• To heat the mixture

• To cool and condense vapor back to liquid

• To filter impurities

• To separate solid particles
