Question

which property of metals allows aluminum to be flattened into thin sheets of aluminum foil?
○ shininess
○ malleability
○ brittleness
○ hardness

Explanation:

To determine the property of metals that allows aluminum to be flattened into thin sheets, we analyze each option:

• Shininess refers to the ability to reflect light, not related to being flattened.
• Malleability is the property of a material to be hammered or rolled into thin sheets, which matches the process of making aluminum foil.
• Brittleness means a material is prone to breaking when stressed, opposite of being flattened.
• Hardness refers to resistance to scratching or indentation, not related to being formed into sheets.

Answer:

B. malleability
