specific volume

Specific volume () is the volume occupied by a unit of mass of a material. It is equal to the inverse of density. Specific volume may be expressed in , or . where, is the volume, is the mass and is the density of the material.For an ideal gas, where, is the specific gas constant, is the molar mass, is the temperature and is the pressure of the gas.

Compare with density .The volume of a unit mass of substance. For example, the specific volume of water at 4°C is 1.00000 mL/g. Specific volume is the reciprocal of density.
