Specific volume is a measure of how much space a substance occupies per unit mass. It is the reciprocal of density and gives an idea of how spread out the particles of a substance are.

Common examples of related units of measurements include liters per kilogram (L/kg) for liquids and gases, cubic meters per kilogram (m^3/kg) for solids, and cubic feet per pound (ft^3/lb) for gases.

• Specific volume is important in determining the compressibility and expansibility of substances.
• It is crucial in engineering applications such as designing refrigeration systems and calculating the efficiency of engines.
• Specific volume is also used in thermodynamics to analyze the behavior of substances under different conditions.
