Both sodium chloride and potassium salts are produced from the Dead Sea ponds. Salt-evaporation works are expanding throughout the world in response to increased manufacture of polyvinyl chloride (PVC) and other chemicals, for which salt is a principal feedstock.
Why evaporation occurs. Heat (energy) is necessary for evaporation to occur. Energy is used to break the bonds that hold water molecules together, which is why water easily evaporates at the boiling point (212Â° F, 100Â° C) but evaporates much more slowly at the freezing point. Net evaporation occurs when the rate of evaporation exceeds the rate of condensation.
