Question

Ishita and Nikita while playing, mixed sawdust, sand and salt. Which methods would you like to suggest them to separate these components?
please give correct answer​

Answer 1

Explanation:

Add water to the mixture. Salt being soluble in water will get dissolved, while sand having higher density will sink and accumulate at the bottom. Saw dust, having less density, will float on the surface of water. Firstly, saw dust is separated out. Then, water is transferred to the other container and sand will remain in the first one. For separating salt from the water, the solution is boiled, as a result water vaporizes and salt is obtained.
