Thermodynamic equilibrium

Thermodynamic equilibrium

A system is said to be at thermodynamic equilibrium if all the intensive properties have the same value throughout the system.

Conditions for thermodynamic equilibrium :

1. Thermal equilibrium :

A thermodynamic system is said to be in thermal equilibrium, if there is no difference in temperature throughout the system.

2. Chemical equilibrium :

Similarly, absence of chemical reaction within the observation makes a thermodynamical system equilibrium.

3. Mechanical equilibrium :

If there is no pressure difference throughout the system the system is said to be in mechanical equilibrium.
