Specific volume is a property of a substance that describes the amount of volume occupied by a unit mass of that substance. In other words, it is the volume of a substance per unit mass.
Specific volume and density are inversely related to each other. While specific volume is the volume per unit mass, density is the mass per unit volume. In simpler terms, specific volume tells us how much space a certain amount of substance takes up, while density tells us how much mass is contained in a certain space.
The unit of measurement for specific volume is typically cubic meters per kilogram (m3/kg) in the SI system. However, it can also be expressed in other units such as cubic centimeters per gram (cm3/g) or liters per kilogram (L/kg).
Specific volume is calculated by dividing the volume of a substance by its mass. This can be expressed as V/m, where V is the volume and m is the mass. It is important to note that specific volume can vary with changes in pressure and temperature, so these factors must be specified when calculating it.
Specific volume is an important property in science because it helps us understand the physical properties of different substances. It is particularly useful in the study of gases, as it allows us to compare the volumes of different gases at the same pressure and temperature. Specific volume is also important in fields such as engineering, thermodynamics, and meteorology.
