← ScienceWhich risk increases when powdered aluminum is dispersed in air during industrial processing?
A)Exothermic oxidation accelerates combustion rate✓
B)Electrostatic charge increases agglomeration rate
C)Inert gas lowers reaction quenching rate
D)Increased moisture promotes hydrolysis rate
💡 Explanation
When aluminum powder is dispersed in air, the significantly increased surface area allows rapid exothermic oxidation which vastly increases combustion rate because of faster radical formation and heat feedback. Therefore explosive combustion results, rather than agglomeration, quenching prevention, or hydrolysis, which depend on different factors.
