Question

Water potetial of pure water at normal temperature and pressure is zero

Answer 1

It is denoted by the Greek letter Psi or Ψ. The water potential of pure water is always taken as zero at standard temperature and pressure. It can be explained in terms of the kinetic energy possessed by water molecules. Water potential is denoted by the Greek letter ψ and is expressed in units of pressure (pressure is a form of energy) called megapascals (MPa). The potential of pure water (Ψwpure H2O) is designated a value of zero (even though pure water contains plenty of potential energy, that energy is ignored)
