Answer 2

filteration process involves the use of a filter paper placed in a filter funnel. The funnel is placed 
in a beaker and the mixture of water and sand is poured into the funnel. The liquid part 
drains through the filter paper into the beaker, leaving the solid sand particles trapped on
the filter. In filtration, the liquid part collected is called the filtrate and the solid bit that 
remained on the filter paper is called the residue.
