← ScienceWhich outcome occurs when a pure substance exceeds triple point temperature under constant volume conditions?
A)Sublimation proceeds without a liquid phase✓
B)Rate of evaporation plateaus exponentially
C)Boiling occurs at a low temperature
D)Supercritical fluid separates into phases
💡 Explanation
Sublimation happens directly because the substance exceeds the triple point; the substance bypasses the liquid phase via sublimation, rather than liquefying and then vaporizing as the increased energy facilitates a solid-gas transition.
