Chapter 36, Problem 3A
Summary Introduction
Introduction:
Water potential is the summation of the potential pressure and the osmotic potential. The potential pressure is the pressure that the water exerts ion another solution. The osmotic potential is defined as the movement of water from solution of higher concentration to the lower concentration solutions.
