How would you obtain clear water from a sample of muddy water?

Answer:

We will obtain clear water from a sample of muddy water by the process of filtration. In this process, we use a piece of cloth for filtering muddy water. Because in a piece of cloth, small holes or pores remain in between the wooven threads. These pores in a cloth can be used as a filter. If the water is still muddy, impurities can be separated by a filter that has even smaller pores. A filter paper is one such filter that has very fine pores in it. A filter paper folded in the form of a cone is fixed onto a funnel. The mixture is then poured on the filter paper. Solid particles in the mixture do not pass through it and remain on the filter and finally the clear water is obtained.
