← ScienceWhich outcome occurs when liquid nitrogen is released into uninsulated closed container causing rapid phase change?
A)Pressure increase exceeding container's burst strength✓
B)Temperature decrease damaging cryogenic instrumentation
C)Oxygen condensation creating explosive mixture
D)Container implosion due to vacuum formation
💡 Explanation
When liquid nitrogen rapidly vaporizes within a closed container due to heat transfer (phase change), the large volume expansion sharply increases the internal pressure because the gas has nowhere to expand, soon exceeding the container's structural limits. Therefore pressure increase leads to burst, rather than other options require different thermal or vacuum processes.
