Question

Which values for solute potential and pressure potential at standard temperature will favour the movement of water from chamber B to chamber A?

• A. ${\psi }_s\left(X\right)=-8bar:{\psi }_p\left(X\right)=7bar$
  ${\psi }_s\left(Y\right)=-3bar:{\psi }_p\left(Y\right)=1bar$
• B. ${\psi }_s\left(X\right)=-5bar:{\psi }_p\left(X\right)=3bar$
  ${\psi }_s\left(Y\right)=-5bar:{\psi }_p\left(Y\right)=2bar$
• C. ${\psi }_s\left(X\right)=-6bar:{\psi }_p\left(X\right)=4bar$
  ${\psi }_s\left(Y\right)=-4bar:{\psi }_p\left(Y\right)=3bar$
• D. ${\psi }_s\left(X\right)=-6bar:{\psi }_p\left(X\right)=5bar$
  ${\psi }_s\left(Y\right)=-7bar:{\psi }_p\left(Y\right)=2bar$

Answer 1

The correct option is C ${\psi }_s\left(X\right)=-6bar:{\psi }_p\left(X\right)=4bar$

${\psi }_s\left(Y\right)=-4bar:{\psi }_p\left(Y\right)=3bar$
