Suppose you have equal amounts of three substances labeled A, B, and C. Then you add 350 mL of water to each, and then wait so that each one has time to absorb all of the water that it can. 25 mL of surface water remains above substance A. 80 mL of surface water remains above substance B. 65 mL of surface water remains above substance C. Which of the substances has the lowest porosity?

Respuesta :

Substance B has the lowest porosity because it absorbed the least amount of water, therefore it has the most liquid above it remaining.
