Question

How would the freezing point of seawater compare with that of pure water?

Freezing Point of Sea water would be lower than that of Pure Water. It is because of salinity of the water

Hope this helps!

Answer 2

The freezing point of pure water is 32° Fahrenheit (0° Celsius). Salt water freezes at a lower temperature than pure water (about 28.4° F and -1.9 C) for the same reason we sprinkle salt on ice in the winter, it lowers the freezing point.
