Which constraint was critical regarding the expansion rate of early Chinese gunpowder weapons?

💡 Explanation

Incomplete combustion limited early gunpowder weapons because the compaction increased, resulting in decreased contact with oxidizer via *surface area limitation*. Higher density lowered the burn rate, therefore weaker projectiles resulted, caused rather than total mass, affecting composition less.
