Question

By convention, the water potential of pure water at standard
temperatures, which is not under any pressure is taken to be zero
How ?

Saman Ahmad · Accepted Answer

Water potential = Solute potential + Pressure potential
Pure water has no solute particles so solute potential is zero
and it is not under any pressure, so pressure potential is also
zero Hence water potential of pure water at standard temperature,
which is not under any pressure, is taken to be zero

By convention, the water potential of pure water at standard temperatures, which is not under any pressure is taken to be zero. How ?
