At equilibrium, the boundary between liquid and vapor does not disappear, but rather stabilizes as the rate of evaporation and condensation become equal. The meniscus, or curved surface of the liquid, is still present but remains constant. Therefore, statement D is false. Statements A, B, and C are all true.
