Answer 2

Answer:

1. don't know

2. Stones and pebbles are separated from sand at a construction site by sieving .

3. You can separate rice grain from the mixture of chalk powder through winnowing

4. Iodine undergoes sublimation i.e changes directly from solid to gas, when heated. So when the mixture of iodine and sand is taken in a China dish and keeping an closed inverted funnel on it, the iodine changes into vapour, gets solidified and will be collected on the walls of the funnel

5. In a mixture of sand and water, the heavier sand particles settle down at the bottom and the water can be separated by decantation. Filtration can be used to separate components of a mixture of an insoluble solid and a liquid.

6. The mixture of sugar-salt solution can be separated by evaporation. If the water is completely evaporated we will get separated sugar from the mixture.
