Water potential is the chemical or potential energy of water molecule . The water potential of pure water is zero. When solute added the solute molecule occupy
more space between the water molecules that reduce the concentration of water molecule per unit of water. Water potential is directly proportional to
the number of water molecule per unit area, when water alone present the potential become stabilized by the intermolecular attraction between the
water molecules (Van der Waals force), but when solute is added the intermolecular attraction force between water molecule reduce and by the
occupation of solute between them.
