We just took adapted to saltwater to freshwater how to do it, make it easier to

looks. The liquid from the sea or ocean. In general, global ocean salinity (salinity) of about 3.5%, or 35 parts per thousand. That means that for every 1 kg of sea salt is found in 35 grams (often found in the form of sodium chloride ions (Na +, Cl-) average density at the surface of the ocean is 1.025 grams per milliliter. Water is denser than fresh water. (Freshwater, with the highest density of 1.000 grams per ml at 4 ° C) because of a heavy sea and salt. Electrostriction (Not conduct electricity But in terms of the electric field), the freezing point of water at -2 Celsius or 28.4 degrees Fahrenheit. In water at a concentration of 35 parts per thousand (35 ppt).
