Which term describes the ability to be drawn into a wire?

• A. Ductility
• B. Solvent
• C. Dipole
• D. London dispersion forces

Answer: (A)

Ductility is the term for a material’s ability to be drawn into a wire. This comes from the material’s capacity to undergo plastic deformation under tensile stress, allowing it to elongate and form a continuous strand without breaking. In metals, metallic bonding and the movement of dislocations enable layers to slide past one another as it’s pulled through a die, producing long wires. The other terms don’t describe this property: a solvent relates to dissolving substances, a dipole refers to internal charge separation in molecules, and London dispersion forces are weak intermolecular attractions, not the controlled elongation needed to make wire.
