Question

You can make a copper wire but not a coal wire. It is because:

• A. copper is malleable but coal is not.
• B. copper is ductile but coal is not.
• C. copper is sonorous but coal is not.
• D. when coal is tried to turn into wire, it start burning.

Answer 1

The correct option is B

copper is ductile but coal is not.

There is a copper wire but not a coal wire. It is because copper is ductile hence can be drawn into wire without being broken but coal being non-metal is not ductile. Hence, when coal is made to turn into wire, it breaks down.
