Witryna17 godz. temu · The sand particles are porous and usually filled with air when dry. As soon as these particles come in contact with water the air-filled cavities get filled with water. Hence, sand absorbs water. However, the sand particles are quite large in size due to which they have high permeability and low surface area. Due to high … WitrynaPorosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a …
