Which risk increased in Ming dynasty muskets due to inconsistent gunpowder?

💡 Explanation

Weaker gunpowder causes unpredictable pressure waves due to uneven burning– leading to potential premature barrel burst, rather than safe projectile firing, because the *pressure differential exceeds barrel strength*; therefore answering A; lower pressures, misfires or recoil would require different powder compositions.

• During ancient Chinese cast iron production using a cupola furnace, which outcome arises from excess sulfur content?
• Which outcome occurs when early cast iron plowshares experience rapid, repeated mechanical stress?
• Which outcome resulted when ancient Chinese blacksmiths unintentionally introduced phosphorous into early cast iron cookware during smelting?
• Which consequence results when the ratio of potassium nitrate to sulfur and charcoal in early Chinese gunpowder varies significantly?
• Which effect results when excessive hydrostatic pressure exceeded mortar strength during Inca stonework construction?
• Which risk increases when a historical stone arch bridge experiences freeze-thaw cycles?
