Which statement best defines a physical characteristic of water?

• A. Things you can see, touch, taste, smell, and hear
• B. Things you can only observe with instruments
• C. Things you can measure by pH
• D. It is something you can see, touch, taste, smell, or hear

Answer: (D)

Physical characteristics are properties you can observe without changing the substance, using your senses. Water’s physical traits include what you can see, touch, taste, smell, or hear—any one of these senses can reveal a observable property like clarity, texture, taste (in the presence of impurities), odor, or even the sound of flowing water. The statement that it can be observed by any one of these senses best captures how we typically identify physical properties. The other ideas aren’t as accurate: relying only on instruments isn’t the definition of a physical property, pH measures chemistry rather than a physical trait, and requiring all five senses at once doesn’t reflect how we observe materials in practice.
