Generally, thermodynamic variables are of two types:

- Intensive Variables
- Extensive Variables

## Intensive Variables in Thermodynamics:

The variables which don’t depend on the amount of matter or mass in a thermodynamic system are called intensive variables.

**Example:** Pressure, temperature, density, surface tension, etc.

## Extensive Variables in Thermodynamics:

The variables which are proportional to the amount of matter or mass in a thermodynamic system are called extensive variables.

**Example:** Volume, magnetic moment, internal energy, entropy, etc.
