← ScienceWhich consequence results when cryogenic liquid nitrogen undergoes rapid adiabatic expansion?
A)Spontaneous autoignition becomes more likely
B)Localized solidification through flash freezing✓
C)Increased convective heat transfer rate
D)System-wide resonance amplification occurs
💡 Explanation
Rapid expansion causes a pressure drop that induces immediate phase change; vigorous boiling through flash freeze, because adiabatic expansion reduces the liquid's temperature below its freezing point very quickly. Therefore liquid instantly freezes rather than autoignition or convective heat increases.
