When water (H2O) contains salt in it, the density or the thickness of the water increases. Else you can say that the space in between the particles of water are occupied with salt molecules. This increases the boiling point and decreases the melting point of water. It also increases the Buoyant force of it.High dense water has high specific heat capacity also.
Conductivity can be used to calculate the salinity of the water.
salinity of the water
Salinity increases as evaporation increases.
Seawater's density varies by temperature and salinity. I.e., cold water is more dense than warm water, and water with a higher salinity (more dissolved salt) is less dense than water with a lower salinity.
Salinity of the ocean water is defined as the dissolved salt content in a body of water. The salinity of the ocean is 3.5%, the salinity increases as you approach the equator and decreases as you approach the poles.
The chemical stability of water is not affected by the salinity; also water decompose at very high temperatures.
Temperature and Salinity.
The effect of temperature is that the warm water is denser than colder water, since the molecules are spread out so the warm water sinks to the bottom. The affect of salinity is that since the water is salanatized it sinks to the bottom while the fresh water floats (due to the amount of salinity).
Surface water has the highest salinity, however it is also the warmest, and because temperature has more effect on the density than the salinity, it rises to the top.
Salinity is a measure of the saltiness of water.
Cold water with high salinity
Temperature, pressure, and common ion effect
Water in water sinks/floats depending mostly on salinity and temperature, note that these two items effect the density of water.
cold water w/ high salinity
Salinity, or saltiness, affects how readily the water changes temperatures as well as its density. Because of this, currents in the water can arise not only from the difference in temperature, but also from the density difference, which comes from the salinity itself.
Conductivity can be used to calculate the salinity of the water.
There are different kinds of process that deeply affects the salinity of ocean water. Continental deflections, Coriolis Effect, convection current and also evaporation.
