Which 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.
