In thermodynamics, the specific volume of a substance (symbol: ν, nu) is a mass-specific intrinsic property of the substance, defined as the quotient of the substance's volume (V) to its mass (m). It is the reciprocal of density ρ (rho) and it is also related to the molar volume and molar mass:
The standard unit of specific volume is cubic meters per kilogram (m3/kg), but other units include ft3/lb, ft3/slug, or mL/g.[1]
Specific volume for an ideal gas is related to the molar gas constant (R) and the gas's temperature (T), pressure (P), and molar mass (M) as shown:
