Question

Instead of discussing osmosis in terms of water concentration, we often speak of the "water potential" of a solution. Considering that the units of pressure are Pascals, which are Newtons per meter squared (1 Pa = 1 N/m?), we can also write the units of pressure in terms of units of energy as an energy density (1 Pa = 1 N/m² = 1 J/mº) since a Joule equals a Newton*meter. Hence, we can speak of the concentration of the water in a solution as a water potential (energy), which simply equals CRT, where C is the molar concentration (n/V which equals moles per meter cubed) and R= 8.314 J/(mol. K) is the ideal gas constant, which, again, equals NakB, where N A is Avogadro's number. Hence, in a system with two regions of solutions with different solute concentrations separated by a membrane permeable only to water, water flows from the region of higher water potential into the region of lower water potential. water flows from the region of higher solute concentration to the region of lower solute concentration. water flows from the region of higher osmotic pressure into the region of lower osmotic pressure. water flows from the region of lower water potential into the region of higher water potential.

Answer 1

Lower concentration to In this case water flows from thigher concentration of solution whater which flows from higher water polential to lower potenhal osmosis lower os mochic pressure to higher os moshe pressure. gt com be said that walles flow from lower. cancen nation to thigher canun nahian So comect of rem water flows foram region of higher walen potentiel Anto | a reguleen of lower water potential water flows from the region of higher water potential into the region of lower water potential. water flows from the region of higher solute concentration to the region of lower solute concentration. water flows from the region of higher osmotic pressure into the region of lower osmotic pressure. water flows from the region of lower water potential into the region of higher water potential.
