Question

${\Psi }_W$ of pure water at standard temperature which is not under any pressure is taken to be

• A. infinite
• B. less than TP
• C. zero
• D. more than OP

Answer 1

The correct option is C zero

Water potential is denoted by the Greek symbol $\Psi$. It is expressed in pressure units such as pascals (Pa). By convention, at standard temperature, the water potential of pure water which is not under any pressure is taken to be zero.
