Thermodynamic Properties

Every system has some physical properties, such as volume, pressure, temperature etc. These characteristics are called properties of the system. All these properties are macroscopic. Thermodynamic properties are classified as following:

1 Intensive Property: The properties of system which are not dependent on the mass of the system are called Intensive property. Example: Pressure, Temperature. Even the system mass is reduced are increased, the temperature and pressure will not vary.

2 Extensive Property: Properties depend on the mass of the system are called Extensive Properties. Example: Volume, Weight, Energy etc. If the mass of the system increased, then the value of the extensive property will also increase.

3 Specific Extensive Properties: Extensive Properties per unit mass are called, the specific extensive property or simply specific property. Example: specific volume- Volume of a substance for unit mass. It remains same and does not depend on the mass of the system. Hence specific property is Intensive property.
