Which term describes a property that relates to the senses and can be measured without changing composition?

• A. Solid
• B. Physical Property
• C. Gas
• D. Chemical Property

Answer: (B)

A physical property is a characteristic you can observe or measure without changing the substance’s identity. It often involves sense-perceived traits like color or odor, or measurable traits such as density, melting point, or hardness. Since no chemical reaction occurs and the composition stays the same, these properties are observed directly rather than altering what the substance is. In contrast, chemical properties describe how a substance behaves in reactions and involve changes to its composition. The options describing a state of matter (solid or gas) aren’t properties themselves, and a chemical property would require a chemical change. So, the term that fits a property related to the senses and measurable without changing composition is a physical property.
