What is water potential ? In detail |
| Answer» \tWater potential is the difference between free energy of water molecules in a pure solvent and free energy of water molecules in a solution.\tSolute potential (Ψs) and pressure potential (Ψp) are the two main components that determine water potential.\tThe greater the concentration of water in a system, the greater is its kinetic energy or ‘water potential’.\tWater potential is denoted by the Greek symbol Psi or Ψ and is expressed in pressure units such as pascals (Pa).\tThe water potential of pure water at standard temperatures is taken to be zero | |
