Question

A wire of about 2 km can be drawn from a gram of gold. This is because of the property called ______.

• A. ductility
• B. malleability
• C. conductivity
• D. sonority

Answer 1

The correct option is A

ductility

• Ductility is the ability of a metal to be drawn into wires.
• While malleability is the ability of a metal to be beaten into sheets.
• When a metal is struck, it produces a deep resonant sound, which is known as sonority.
• Conductivity in metal is a measure of a material's ability to allow heat, or electricity to pass through.

Thus, the property of gold by which it can be drawn into a wire of about 2 km is ductility.
