    Which of the following processes is useful to collect pure water from a solution of sugar and water or salt and water?

    A)  Filtration          

    B)         Evaporation

    C)  Distillation      

    D)         Crystallisation

    Correct Answer: C

    Solution :

     The solution of salt and water or sugar and water is heated so that water gets evaporated. When water starts evaporating, it is collected and condensed. The water thus obtained is pure water and is called distilled water. As the processes involved are evaporation and condensation, it is called distillation.
