Systems approach equilibrium over time from "summary" of Thermodynamics and an Introduction to Thermostatistics by Herbert B. Callen
The systems approach is a powerful tool for understanding the behavior of physical systems. In this approach, we consider a system and its surroundings as a whole, rather than focusing solely on the system itself. This allows us to take into account the interactions between the system and its environment, which can have a significant impact on the system's behavior. Equilibrium is a key concept in thermodynamics, and it plays a central role in the systems approach. When a system is in equilibrium, its properties do not change over time. This means that the system is in a stable state, with no net flow of energy or matter between the system and its surroundings. Over time, a system will tend towards equilibrium. This is because systems naturally seek to minimize their internal energy and maximize their entropy. When a system is not in equilibrium, there are driving forces that push it towards equilibrium. These driving forces can be thought of as the "forces of nature" that act on the system, causing it to change until it reaches a state of equilibrium. The systems approach allows us to understand how systems evolve over time as they move towards equilibrium. By considering the system and its surroundings as a whole, we can account for the interactions between the system and its environment that drive the system towards equilibrium. This holistic view of systems allows us to predict how they will behave over time and understand the underlying principles that govern their behavior.- The systems approach provides a powerful framework for understanding the behavior of physical systems. By considering systems and their surroundings as a whole, we can analyze how systems evolve over time and move towards equilibrium. This approach allows us to take into account the interactions between the system and its environment, providing insights into the fundamental principles that govern the behavior of physical systems.
