What does density compare in relation to objects?

Density specifically measures how much mass is contained in a given volume of an object. It is calculated by dividing the mass of the object (usually in grams or kilograms) by its volume (measured in cubic centimeters or liters). This ratio gives a direct comparison of the weight of an object to the space it occupies.

In practical terms, higher density means that more mass is packed into a certain volume, while lower density indicates that similar mass is spread over a larger volume. Understanding density is crucial for various applications in science and engineering, such as buoyancy, material selection, and in calculating the efficiency of different substances.

Other options do not accurately describe density. For instance, density is not concerned with temperature or shape, nor does it relate to gravitational pull, which pertains to forces acting on an object rather than the intrinsic properties that density measures.
