Characteristics that you can observe without changing the identity like color, shape, size, melting point, etc.

• A. Physical change
• B. Chemical property
• C. Matter
• D. Physical property

Answer: (D)

Physical properties describe matter as it is, without changing its identity. Observing color, shape, size, and melting point tells you about the material itself—how it looks or behaves under conditions—without turning it into something else. The melting point is a specific property that indicates the temperature at which a solid becomes a liquid, which helps identify or characterize the substance without altering what it is.

In contrast, a chemical property would involve how the substance reacts to become a new substance (like reacting with acids or burning), and a physical change is a change in form or state that still leaves the substance the same material. So the best choice is physical property.
