← HistoryWhich outcome resulted from the intentional addition of arsenic to copper during the Early Bronze Age?
A)Increased metal hardness and durability✓
B)Enhanced resistance to oxidation and rust
C)Improved thermal conductivity for casting
D)Reduced melting temperature for easier smelting
💡 Explanation
When arsenic was alloyed with copper, solid solution strengthening occurred because the arsenic atoms distorted the copper lattice, impeding dislocation movement. Therefore increased hardness and durability resulted, rather than oxidation resistance, thermal conductivity or easier smelting, which demand different alloy additions and mechanisms.
