hich Dear student,      
Please find below the solution to the asked query                                                              

The pure water does not contain ions and so, the particles of pure water can easily evaporate into the atmosphere. In case of seawater, salt particles are present. These occupy the surface area of seawater and blocks the process of evaporation of solvent particles.
