← ScienceWhich consequence results when rapid decompression flash-boils cryogenic liquid nitrogen?
A)Nitrogen embrittlement decreases structural integrity.✓
B)Excessive latent heat absorption occurs.
C)Fluid kinematic viscosity significantly increases.
D)Sublimation converts gas into solid.
💡 Explanation
Rapid decompression induces flash-boiling because the phase transition proceeds via rapid volumetric expansion; therefore, nitrogen embrittlement accelerates rather than the other effects, due to the reduced ductile fracture resistance at cryogenic temperatures.
