Is water potential measurable? How is it represented and measured?

Explanation

### Step-by-Step Solution:

1. **Understanding Water Potential**:
- Water potential is a measure of the potential energy of water in a system. It indicates the tendency of water to move from one area to another.
- Water molecules possess kinetic energy, which is influenced by the number of free water molecules present. More free water molecules lead to higher kinetic energy and, consequently, a higher water potential.

2. **Maximum Water Potential**:
- In pure water, where there are no solutes, the water potential is at its highest. The maximum water potential is defined as 0. This serves as a reference point for measuring the water potential of other solutions.
