ductility
conductivity
malleability
luster
question 3
the ability of a substance to be manipulated and hammered or rolled into flat sheets is called...
luster
ductility
conductivity
malleability

Explanation:

First Question (The ability of a substance to transfer heat or electricity...):

• Ductility: Ability to be drawn into wires, not heat/electricity transfer.
• Conductivity: Defined as the ability to transfer heat or electricity.
• Malleability: Ability to be hammered into sheets, not heat/electricity transfer.
• Luster: Refers to shine/appearance, not heat/electricity transfer.

• Luster: Shine/appearance, not related to shaping into sheets.
• Ductility: Ability to be drawn into wires, not into sheets.
• Conductivity: Heat/electricity transfer, not shaping.
• Malleability: Defined as the ability to be hammered or rolled into flat sheets.

Answer:

B. conductivity

Second Question (The ability of a substance to be manipulated and hammered or rolled into flat sheets...):
