Q3-ans=The principle for separation of immiscible liquids is carried out by using a separation funnel. The two liquids are put into the funnel and left to sit down to form two layers for a short period of time. The funnel tap is opened and the underlying liquid is allowed to run.

Therefore, the particles in both sol and solution are invisible to the naked eye while the particles in suspension are visible to the naked eye.

Q8-ans= The separation of a liquid mixture by passing it through a material through which some parts of the mixture travel further than others.
