The reciprocal of density is what property?

• A. Specific Volume
• B. Mass
• C. Temperature
• D. Pressure

Answer: (A)

The reciprocal of density is specific volume. Since density is mass per volume (ρ = m/V), flipping it gives V/m, which is defined as the specific volume. It represents how much space a unit mass occupies, with units of m^3/kg, and is used to relate volume and mass in thermodynamics (for example, in the ideal gas context, the specific volume connects to temperature and pressure). The other quantities don’t fit because mass is simply the amount of matter, while temperature and pressure are not measures of how much space a given mass occupies.
