What is the water potential of pure water?
Understand the Problem
The question is asking for the water potential of pure water, which is a concept in biology and environmental science referring to the potential energy of water in a system compared to pure water. In pure water, the water potential is usually considered to be zero, as it serves as a reference point.
Answer
zero at standard temperature and pressure
The water potential of pure water is zero at standard temperature and pressure.
Answer for screen readers
The water potential of pure water is zero at standard temperature and pressure.
More Information
Water potential is a measure of the potential energy in water, specifically the potential for water to move from one area to another. Pure water at standard temperature and pressure is the reference point with a water potential of zero.
Tips
A common mistake is confusing water potential with solute potential or pressure potential. Remember that pure water (no solutes) always has a water potential of zero.
