Not if you look at the sample sentence provided at that link: Democrats faired marginally better in the study, ringing in at 31 percent.. I believe that using that sentence is an error on dictionary.com's part.
Porosity and Permeability Lab. The terms porosity and permeability are related. ï· porosity â the amount of empty space in a rock or other earth substance; this empty. space is known as pore space. Porosity is how much water a substance can hold. Porosity is usually stated as a percentage of the materialâs total volume. ï· permeability â is how well water flows through rock or other earth substance.
Believe it or not, some porous rocks are considered impermeable. No rock is completely impermeable, but some porous rocks like shale and pumice are mostly impermeable, because â¦ the pores are not interconnected, thus not allowing fluids or gases to pass through them.This is why shale makes a good cap-rock, and pumice floats instead of sinking.2 people found this useful. A non porous rock is a rock which has interlocking grains so water can't get into it. A porous rock is like a sponge and a non porous rock is like a stone.
