WebAt the lower atmospheric pressure on the top of Mount Everest, pure water boils at about 154 °F (68°C). In the deep oceans, under immense pressure, water remains liquid at temperatures of 750°F (400°C) around hydrothermal vents. Pressure also alters the melting/freezing point. WebJan 24, 2024 · Salt lowers the freezing point because it draws moisture from the air surrounding the ice crystals. This reduces the surface tension between the ice crystal and the surrounding liquid. As a result, the ice crystals become smaller and more numerous, allowing them to slide past each other more easily.
