Non-Equilibrium Thermodynamics primarily deals with systems that are not in a state of equilibrium. It emphasizes the dynamic processes and transformations occurring over time, often focusing on how systems evolve and interact with their surroundings. Time dependency of systems is crucial, as it describes how systems change and respond to internal and external influences. Transformation processes also play a significant role, as they capture the energy and matter changes occurring within non-equilibrium systems. Open system interactions highlight the exchanges of energy and matter with the environment, which are essential for understanding the behavior of systems in non-equilibrium states.

In contrast, equilibrium conditions refer to states where the system's macroscopic properties are stable and no longer change over time. Once a system stabilizes and reaches equilibrium, many of the complexities that Non-Equilibrium Thermodynamics addresses become irrelevant, since the focus moves away from dynamic changes to a static analysis of the equilibrium state. Therefore, the approach and principles of Non-Equilibrium Thermodynamics do not concentrate on the conditions after a system stabilizes, making that aspect distinct from its core focus.
