Properties of the Thermodynamics System

Some of the properties of a system depend on its mass or size whereas other properties do not depend on its mass or size.

Properties of the system:

 

Intensive and extensive properties

 

Some of the properties of a system depend on its mass or size whereas other properties do not depend on its mass or size. Based on this, the properties of a system are grouped as extensive property and intensive property.

 

Extensive properties:


The property that depends on the mass or the size of the system is called an extensive property.

 

Examples: Volume, Number of moles, Mass, Internal energy, etc.,

 

Intensive properties:

 

The property that is independent of the mass or the size of the system is called an intensive property.

 

Examples : Refractive index, Surface tension, density, temperature, Boiling point, Freezing point, molar volume, etc.,
