... as an important variable. Since vapor pressure is the force per unit area resulting from molecular collisions, and osmosis occurs with liquid on both sides of the membrane, I proposed that free molecules must exist in pure liquids and solids. Osmosis; evaporation; condensation; boiling; applications; mathematical...
