Which outcome occurs when a closed cryogenic tank containing liquid helium experiences rapid depressurization?

💡 Explanation

When rapid depressurization occurs, the phase transitions cause rapid vaporization because as the pressure decreases, liquid helium boils, increasing the gaseous helium volume attempting to maintain equilibrium leading to tank pressure increase . Therefore, boil-off results, rather than solidification, film creep, or decomposition, which need different conditions.
