← ScienceWhich risk greatly increases when pressurizing refrigerant beyond its critical point?
A)Indistinct vapor-liquid phase transition✓
B)Supercooling to lower energy phase
C)High chance of endothermic reaction
D)Decreased rate nucleate boiling onset
💡 Explanation
An indistinct vapor-liquid phase transition occurs beyond the critical point because supercritical fluids no longer exhibit a distinct phase boundary between liquid and gas. Therefore, mixtures do not easily separate, rather than separate phases occurring at lower pressures.
