Answer 1

Answer :

i ) to separate the mixture of chalk sugar and water , you will have to use the process of Sedimentation and Decantation , In this method , you will have to leave the solution poured into a beaker for a while to set still ( this process is called Sedimentation ), then after a while when the solution ( now of water and sugar only as the chalk will be settled down ) is settled , pour the sugar and water solution into another beaker ( this process is called Decantation )

In this way the chalk will get separated from the solution of water and sugar .

Now , Separate water and sugar solution , u will have to use the method of Evaporation . In this method , u will have to leave the solution under the heat of the Sun for a few days ; in this way , water will be evaporated by Sun and the sugar will stay left in the container
