← ScienceWhich effect occurs when pressurized liquid hydrogen undergoes rapid isenthalpic expansion?
A)Vapor-liquid phase explosion occurs✓
B)Gas temperature quickly approaches zero
C)Fluid enters supercritical carbon state
D)Hydrogen auto-ignites spontaneously there
💡 Explanation
Vapor-liquid phase explosion occurs because rapid expansion leads to sudden pressure reduction; with consequent explosive boiling via rapid vaporisation of the liquid, creating large volumes of gas. Therefore an energetic phase explosion occurs, rather than simple boiling, triggered by the metastable liquid suddenly reaching its spinodal.
