← HistoryWhich problem accelerated bronze cannon degradation during 17th-century naval warfare?
A)Rapid bore corrosion from saltpeter residue✓
B)Breech explosions caused by thermal expansion
C)Barrel sagging due to insufficient annealing
D)Oxidation from exposure to seawater spray
💡 Explanation
When saltpeter residue accumulated in cannon bores, electrochemical corrosion occurred creating a galvanic cell with bronze components because of the chloride ions in seawater triggering chemical reactions. Therefore bore corrosion resulted, rather than explosions, sagging or oxidation, all of which rely on distinct environmental factors and material failures.
