How does the filter paper absorb water? Is it due to capillary action or osmosis? Absorption of water by filter paper is due to capillary action
The filter paper has pores that allow liquid to pass through them. When the liquid passes through these pores, they get smaller. This causes the pressure inside the pores to increase. As a result, the liquid gets squeezed out of the pores.
Capillary action is the force exerted by a fluid on a surface. Capillarity is the tendency of liquids to flow into narrow spaces. Osmosis is the movement of solvent molecules from a region of higher solute concentration to a region of lower solute concentration.
