Answer :

Saltwater is denser than freshwater due to its high salinity, and its freezing point is lower than freshwater.

What is saltwater?

Saltwater, or seawater, has several unique characteristics that differentiate it from freshwater. Two special characteristics of saltwater are its salinity and its density.

Salinity refers to the concentration of dissolved salt and other minerals in seawater. On average, seawater has a salinity of around 35 parts per thousand (ppt), or 3.5%, making it much saltier than freshwater.

The high salinity of seawater affects its density, making it denser than freshwater. This means that objects will float higher in saltwater than in freshwater, and it also affects ocean currents and circulation patterns. The high salinity of seawater also affects its freezing point, which is lower than that of freshwater, making it more resistant to freezing.
