veepotentsiaali
Veepotentsiaali, also known as water potential, is a thermodynamic concept that describes the tendency of water to move from one area to another. It is a measure of the free energy of water per unit volume. Pure water at standard atmospheric pressure has a water potential of zero. The presence of solutes, pressure, or matric forces can lower the water potential, making it negative.
Water moves from an area of higher water potential to an area of lower water potential. This
Factors affecting water potential include solute concentration (osmotic potential), pressure (pressure potential), and the interaction of
