Which outcome accelerates in song-dynasty iron cannon when moisture contacts poorly combined gunpowder constituents?

💡 Explanation

Corrosion accelerates because galvanic corrosion is caused by electrochemical action occurring directly between the iron and gunpowder constituents in the presence of water causing oxidation reduction, therefore, iron is lost from the barrel rather than pressure change.
