Which outcome accelerated oxidation within ancient bronze cannon barrels?

💡 Explanation

Differential aeration caused increased corrosion, because oxygen concentration variations induced electrochemical potential differences that accelerated oxidation at oxygen-starved regions; therefore, localized corrosion, rather than uniform corrosion, occurred.

• Which risk increased for medieval stone fortifications lacking rounded bastions?
• Which risk increased as Viking longships used increasingly longer rigging?
• Which consequence occurred when early sextant mirrors had imperfections?
• Which risk increased for Roman legionary cohorts during sieges when constructing vineae (mobile siege sheds) from green wood?
• Which outcome results from the use of forced-air induction in early piston-engine aircraft operating at high altitude?
• Which consequence arises when tides exceed design constraints for Viking rope bridges?
