Specific Volume

Specific volume is a measure of how much space a unit mass of a substance occupies. It’s calculated by dividing the total volume of the substance by its mass. Think of it as the "spread-outness" of a material—how much space each kilogram or pound of it takes up. For example, in gases like air, high specific volume means the gas is more spread out, while in solids, it’s very compact with a low specific volume. This property helps engineers understand and predict how materials behave under different conditions, such as temperature and pressure.
