← ScienceWhich consequence results when rapid sublimation of dry ice cools a sealed container?
A)Significant internal pressure decrease occurs✓
B)Water vapor condenses excessively inside
C)Oxygen concentration rapidly increases inside
D)Material undergoes exothermic polymerization inside
💡 Explanation
Decreased pressure results because rapid sublimation converts solid CO2 to gas, and Le Chatelier’s principle dictates shifting equilibrium; therefore, a vacuum forms as pressure decreases, rather than condensation or increased oxygen because those processes are kinetically unfavorable.
