Evaporation isn't the only process that is responsible for the conversion of liquid into vapor. There is another process called vaporization which occurs at any temp. above the melting point of the liquid ! At a temp. more than or equal to the boiling point of a liquid , the process of conversion of a liquid into vapor is the fastest ! While, it is comparatively slower as temperature falls below the boiling point. That is why when water in a container is kept for a long time , there appear traces of the salts dissolved in it !
