Answer :
I’m pretty sure copper is used for both of those things because it’s a better conductor of heat and electricity.
Answer:
Fe has fewer valence electrons than Cu. Fe has a lower conductivity than Cu. The lower conductivity of Fe makes it less useful for wiring and cookware. Fe is less malleable and ductile than Cu. The lower malleability and ductility of Fe make it less easy to form into wires or sheets.
