Vedclass · Answer

(A) Water potential $(\Psi_w)$ is the potential energy of water in a system compared to pure water. When pressure greater than atmospheric pressure is applied to pure water or a solution, it is called pressure potential $(\Psi_p)$. Pressure potential is usually positive. The formula for water potential is $\Psi_w = \Psi_s + \Psi_p$. Since $\Psi_p$ increases with the application of positive pressure, the total water potential $(\Psi_w)$ also increases. Therefore, applying pressure greater than atmospheric pressure increases the water potential.

If a pressure greater than atmospheric pressure is applied to pure water or a solution, its water potential:
