深海热液区的压力随深度增加而增大，每深 10 米约增加 1 个大气压。在 2000 米深处，压力约为 200 个大气压，此时水的沸点可升高到 370℃以上。热液喷口的水温虽达 400℃，但因周围海水压力更高（超过 200 大气压），水不会沸腾，仍保持液态，这种超临界状态的水对矿物质的溶解能力极强。

Why does "the water temperature in deep-sea hydrothermal areas reach 400℃ but does not boil"?

The pressure in deep-sea hydrothermal areas increases with depth, increasing by about 1 atmosphere every 10 meters. At a depth of 2000 meters, the pressure is about 200 atmospheres, and the boiling point of water can rise to above 370℃. Although the water temperature at hydrothermal vents reaches 400℃, the surrounding seawater pressure is higher (more than 200 atmospheres), so the water will not boil and remains liquid. This supercritical water has a strong ability to dissolve minerals.
