Which process is involved in the removal of salt from sea water?

Ans.
The process used to remove salt from seawater is called desalination. This process converts saline water into fresh water suitable for drinking and other uses.

One common method of desalination involves evaporation followed by condensation. In this method, seawater is heated so that water evaporates and leaves the salt behind. The water vapour is then cooled and condensed to form pure water.

Another modern method is reverse osmosis, which uses special membranes to remove salts and impurities from seawater.
