← ScienceWhich outcome results when a closed container of water exceeds its critical temperature and pressure?
A)Distinct liquid-gas phases disappear✓
B)Water spontaneously freezes into ice
C)The container undergoes mechanical failure
D)Water becomes a perfect insulator
💡 Explanation
When critical temperature and pressure are exceeded, the heat provides enough energy for molecules to overcome intermolecular forces. This allows continual mixing of vapor and liquid phases. Therefore, separate distinct liquid-gas phases disappears, rather than freezing, container failure, or insulation, which require other, distinct thermodynamic conditions.
