Which property describes the weight of material relative to its volume?

• A. Density
• B. Volume
• C. Mass
• D. Weight

Answer: (A)

Density describes how much matter is packed into a given volume. It’s a measure of how heavy something is for its size, because weight is proportional to mass under gravity. Put simply, density = mass per unit volume, with common units like g/cm^3 or kg/m^3. This is why a small piece of dense material feels very heavy for its size, while a less dense material of the same size feels lighter. Volume just tells you how big something is, mass tells you how much matter there is, and weight is the gravitational force on that mass; density combines mass and volume into a single property that directly relates weight to volume.
