then i will evaporate the water in the water-sugar solution.
and we have seperated  sugar and sand

Answer 2

To separate sugar from its mixture with sand, a proportionally large amount of water is added to the mixture and shaken vigorously to allow the sugar to dissolve. The solid-liquid mixture is filtered using a porous material to retain the sand on the filter and to allow the liquid portion to pass through. The liquid contains the sugar originally present in the solid mixture.
