Which consequence occurred historically when iron reacted with gunpowder?

💡 Explanation

Bore corrosion accelerated in early gunpowder weaponry because the sulfurous products reacted galvanically on the iron: Rapid oxidation consumed the barrel rather than improving performance. Therefore the barrel's integrity was compromised, and embrittlement didn't happen.

• Which outcome resulted when iron impurities weakened early cast iron plows used in Chinese agriculture?
• In the Inca empire, which risk increased when the quipu (knotted string records) decayed physically under damp conditions?
• Which risk increases when an ancient rope bridge's tension reaches material yield strength?
• During the Song Dynasty, which risk increased as the carbon content increased beyond hypoeutectic composition within cast iron crossbow trigger mechanisms?
• Which problem arose when early astrolabes were constructed from wood?
• Which consequence weakens a city's Byzantine diplomatic leverage during a siege?
