Question

4. Two objects have the same volume but different masses. The object with more mass has:
A. Lower density
B. Higher density
C. The same density
D. No density
5. Which property can be used to identify an unknown substance?
A. Mass
B. Volume
C. Density
D. Color

Answer 1

4. B — Higher density. (Density = mass/volume, so if volume same and mass greater, density is greater.)
5. C — Density. (Density is a characteristic property useful for identifying substances; mass or volume alone are not unique identifiers, and color can be ambiguous.)
