Which of the following characteristics is NOT a physical characteristic of water?

• A. Taste
• B. pH Level
• C. Color
• D. Temperature

Answer: (B)

The choice indicating that pH level is not a physical characteristic of water is accurate. Physical characteristics of water typically include attributes that can be observed or measured without changing the water's chemical composition. These are features such as taste, color, and temperature, which are indeed physical characteristics because they relate to the sensory and measurable properties of water. pH level, on the other hand, is a measure of the hydrogen ion concentration in water, which indicates its acidity or alkalinity. It is considered a chemical characteristic because it reflects the chemical interactions and reactions that can occur in the water rather than just its observable properties. Thus, while taste, color, and temperature can be directly perceived or measured in a straightforward manner without altering the water itself, pH level involves a deeper understanding of the water's chemical behavior and composition.
