Question

Water potential of pure water at standard temperature is equal to
A. 10
B. 20
C. 0
D. None of the above

Answer 1

The calculation of the available energy in water is water potential. The capacity of water relies on the accumulation of solutions in water. Water capacity is the indicator of water's potential energy which drives water flow through plants.

Complete Answer:
The potential of water is often known as water's chemical potential. The higher the water content in a device, the greater it is the capacity for kinetic energy or water. In terms of pressure, the soil's water potential is quantised. The water potential of pure water at a normal temperature, which is not under any pressure, is known to be zero by convention. If a solvent is dissolved in pure water, the solution contains less free molecules of water and reduces the concentration of water, decreasing the capacity for water.

Additional Information:
- Compared with pure water, water potential is the potential energy of water in a system, where all temperature and pressure are held the same. It can also be defined as a measure of how water molecules in a given atmosphere or structure can travel freely.
- The potential of water is never positive, but it has a maximum value of zero, which is the ambient pressure of pure water. When it comes to impure water or water that has solutes in it the more negative water potential becomes when there is more solvent, so the solvent molecules will absorb the water molecules and limit their ability to travel.

So the correct option is C, 0.

Note: The most common material in the human body is water, the only substance on earth that can exist as a vapour, liquid, and solid. There is virtually no pure water in nature because of its ability to dissolve various compounds in vast quantities.
