Ductility describes which property?

• A. Ability to be dissolved in water
• B. Ability to be drawn into wires
• C. Capacity to melt at high temperature
• D. Measure of how fast a chemical reacts

Answer: (B)

Ductility is a material’s ability to undergo substantial plastic deformation under tensile stress, allowing it to be drawn out into thin wires. This means the material can stretch into a long, continuous strand without breaking, which is why metals like copper and gold are commonly used for wires. The key idea is that ductile metals don’t just snap when pulled; they elongate and flow to form wires. This property is different from dissolving in water (solubility), melting at high temperature (melting point), or reacting quickly (reaction rate).
