← ScienceWhich risk increases when liquid nitrogen rapidly undergoes phase transition in poorly vented electronics?
A)Over-pressurization and structural rupture✓
B)Reduced heat transfer capability
C)Dielectric breakdown of insulators
D)Increased component corrosion rate
💡 Explanation
Rapid phase transition causes substantial volume increase because the Leidenfrost effect prevents even boiling. The resulting pressure rise increases rupture risk, therefore correctly identifying this over-pressure event, rather than falsely assuming the cooling outcome.
