WebSea Water, Freezing of. The density of ocean water is determined by its salinity (or salt content) and temperature. The saltier and/or colder the water is, the denser it is. Salt water is most dense at its freezing point, unlike fresh water, which is most dense at about 3.9°C (39.0°F). Oceans are highly stratified: deep ocean water is heavy ... WebJul 17, 2024 · For fresh water, the freezing point is 32 degrees Fahrenheit. This means that when the weather outside dips below 32 degrees, the water will turn to ice. However, salt water has a lower freezing point than fresh water. In fact, saltwater can stay liquid even when the temperature outside is well below freezing.
WebThe difference between the air temperature and the freezing point of salt water is bigger than the difference between the air temperature and the freezing point of freshwater. This makes the ice with salt on it melt faster. ... Fresh water freezes at 32 degrees F (0 degrees C). Salt water freezes at lower temperatures, depending on how much ...
