Question:
The water potential of pure water at standard temperature and pressure is
The water potential of pure water at standard temperature and pressure is
Show Hint
Pure water: 0.0 MPa at STP.
Water moves from higher (less negative) to lower (more negative) water potential.
Water moves from higher (less negative) to lower (more negative) water potential.

- -1.0 MPa
- 0.0 MPa
- +1.0 MPa
- Infinite MPa
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of water potential.
Step 2: Detailed Explanation:
The water potential of pure water at standard temperature and pressure (STP) is 0.0 MPa.
This is the reference point for water potential measurements.
All other solutions have negative water potential (due to solutes, pressure, etc.).
Thus, pure water has a water potential of 0 MPa.
Step 3: Final Answer:
Thus, the water potential of pure water is 0.0 MPa, which corresponds to option (B).
