Kamal was told by his mother to pour water through a thin cloth into another container to further purify the water.

Answer 1

$\large{\underbrace{\underline{\color{magenta}{\bf{ANSWER}}}}}$

a].When sand is added to water it either hangs in the water or forms a layer at the bottom of the container. Sand therefore does not dissolve in water and is insoluble. It is easy to separate sand and water by filtering the mixture.

b]. The water filtered by kamal is not safe to drink .

If you run out of water, or cannot carry enough water with you for your entire trip, you may need to source drinking water from natural water sources.
