What is the Difference Between Volume and Specific Volume?
🆚 Go to Comparative Table 🆚The main difference between volume and specific volume lies in the fact that volume is an extensive property, while specific volume is an intensive property.
- Volume: This is a thermodynamic property of a substance and refers to the amount of space occupied by it. Volume is usually measured in cubic meters (m³).
- Specific Volume: This is a property of materials and represents the relationship between mass and volume of a substance. It is defined as the number of cubic meters occupied by one kilogram of a particular substance. The standard unit for specific volume is meters cubed per kilogram (m³/kg or m³·kg⁻¹). Specific volume is the reciprocal of density and can be calculated using the equation: $$\nu = \frac{V}{m} = \frac{RT}{PM}$$.
In summary:
- Volume is a thermodynamic property that refers to the amount of space occupied by a substance.
- Specific volume is an intensive property that represents the relationship between mass and volume of a substance.

Comparative Table: Volume vs Specific Volume
Here is a table comparing the differences between volume and specific volume:
Property | Volume | Specific Volume |
---|---|---|
Definition | Volume refers to the amount of space occupied by a substance or object. Specific volume refers to the volume of a substance per unit mass. | |
Equation | Volume: V = nRT / P. Specific volume: ν = V / m. | |
Units | Volume is measured in cubic meters (m³).. Specific volume is measured in cubic meters per kilogram (m³/kg).. | |
Nature of property | Volume is an extensive property, meaning it depends on the amount of substance. Specific volume is an intensive property, meaning it is independent of the amount of substance. | |
Applications | Volume is used to describe the amount of space occupied by a substance in various fields like physics, chemistry, and engineering. Specific volume is used in engineering, chemistry, and physics to make predictions concerning the behavior of gases under changing conditions and for volume, molar volume, and partial molar volume calculations. |
In summary, volume is a measure of the space occupied by a substance, while specific volume is a measure of the volume per unit mass of a substance. Volume is an extensive property, while specific volume is an intensive property.
