← ScienceWhich outcome occurs when rapid depressurization of carbon dioxide fire extinguisher initiates?
A)Sublimation cools the extinguisher body
B)Adiabatic cooling forms dry ice✓
C)Vaporization warms the nozzle surface
D)Deposition rapidly heats the environment
💡 Explanation
Adiabatic cooling creates dry ice, as the rapid expansion of carbon dioxide causes its temperature to drop below the sublimation point during phase transitions. Because it is an expansion driven process, forming dry ice, therefore there is no external impact. It's adiabatic cooling rather than some other thermal effect.
