What is specific volume?

• A. The weight of a material per volume
• B. The ratio of volume to mass
• C. The space occupied by a solid
• D. The density of a liquid

Answer: (B)

Specific volume is defined as the ratio of the volume of a substance to its mass. This means it measures how much space a given mass of material occupies, providing a direct relationship between the volume that the material takes up and its weight. It is an important property in fields such as thermodynamics and fluid mechanics, as it helps in understanding the behavior of gases and liquids under various conditions. The specific volume is typically expressed in units like cubic meters per kilogram (m³/kg) and is crucial for applications that involve the calculation of density and buoyancy.

The other options do not accurately capture the concept of specific volume. For instance, while density is related and describes how much mass is contained in a specific volume, it is not the same as specific volume, which is its reciprocal. Additionally, the notion of specific volume does not refer to the weight of a material per volume, the space occupied specifically by solids, or just the density of liquids.
