Which term describes the relationship between the space an item occupies and how much it weighs?

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

Answer: (A)

Density is the measure of how much mass is packed into a given volume. It captures the relationship between the space an object occupies and how heavy it is because density equals mass per unit volume. If an object has a lot of mass in a small space, its density is high; if the same mass spreads out over a larger volume, the density is low. Volume describes the space itself, mass is the amount of matter, and “weight ratio” isn’t a standard term, so density best fits the described relationship.
