Compare and contrast the physical properties of seawater and freshwater What will be an ideal response?

Seawater is about 96.5% pure water and 3.5% dissolved solids and gases. The solids
dissolved in seawater change its thermal characteristics, lowering its latent heat by about 4%.
Only 0.96 calorie of heat energy is needed to raise the temperature of 1 gram of seawater by
1°C. The dissolved solids also interfere with the formation of the ice lattice, acting as
“antifreeze” to lower the freezing point. The saltier the water, the lower the freezing point.
Seawater’s density simply increases smoothly with decreasing temperature until it freezes.
The crystals that form are pure water ice, with the seawater salts excluded. The leftover cold,
salty water is very dense. Some of this water may be trapped among the ice crystals, but most
is free to fall toward the seabed, pulled rapidly downward by its great density. Seawater
evaporates more slowly than freshwater under identical circumstances because the dissolved
salts tend to attract and hold water molecules. The latent heat of evaporation, however, is
essentially the same for both freshwater and seawater. Salts are left behind as seawater
evaporates.
