1.	The water potential (ψp) of pure water at standard temperature and atmospheric pressure is(a) 0(b) 0.5(c) 1.0(d) 2.0
Answer» Answer is : (a) 0 Pure water at standard temperature and atmospheric pressure has a water potential of zero. As solute is added, its value becomes more negative. This causes water potential to decrease. Water potential is the measure of the potential energy in water. It is denoted by the Greek letter ψ (Psi) and is expressed in units of pressure (pressure is a form of energy) called Mega Pascals (MPa).

Answer»

Answer is : (a) 0

Pure water at standard temperature and atmospheric pressure has a water potential of zero. As solute is added, its value becomes more negative. This causes water potential to decrease. Water potential is the measure of the potential energy in water. It is denoted by the Greek letter ψ (Psi) and is expressed in units of pressure (pressure is a form of energy) called Mega Pascals (MPa).
