Question

Potential energy of water is
A. Osmotic potential
B. Water potential
C. Gravity potential
D. Pressure potential

Answer 1

This potential is usually expressed as potential energy per unit volume, and the Greek letter ${\rm{\Psi }}$ is most often represented.

Complete answer:
Potential energy is an energy that is contained in an object or material, or retained in it. The position, arrangement or state of the item or material is the basis for this potential energy. It is an energy that we can think of as the 'potential' to function. Potential energy is the energy contained by an object because of its location in relation to other objects, pressures, electrical charges or other influences. Popular types of potential energy include an object's gravitational potential energy that depends on its distance and mass from the center of mass of another object; an extended source's elastic force potential; and electric charging potential energy within an electrical field.

Water potential in the reference conditions represents the potential water energy per unit volume compared to pure water. Water potentials measure the tendency of the water, because of osmosis, gravity, mechanical and matrix effects for example capillary action, to move from one location to another. The water potential concept has been useful in the understanding and measurement of water motion in plants, animals and land. Water potentials are usually expressed as potential energy per unit volume, and the Greek letter ${\rm{\Psi }}$ is most often represented.

Thus, the correct answer is option B. i.e., Water potential.

Note: Potential energy is the energy contained by an object due to its location in relation to other objects, pressures, electrical charges or other influences. Water potentials measure the tendency of the water, because of osmosis, gravity, mechanical and matrix effects for example capillary action, to move from one location to another.
