- Equilibrium Systems
In summary, a non-equilibrium system is a physical system that is not in a state of thermodynamic equilibrium, characterized by the presence of energy or matter flow. These systems differ from equilibrium systems in that they are constantly changing and do not have a steady state. Examples include chemical reactions, living organisms, and weather patterns. Understanding non-equilibrium systems is important for various fields of science and can lead to advancements in technology and medicine. However, their complexity and emergent behavior pose challenges in studying and controlling these systems.

A system that is not in equilibrium. 
It depends on the problem your dealing with, but can usually be figured out by the context. For example, a system not in mechanical equilibrium means that the sum of the forces does not equal zero. A system outside of thermal equilibrium means that there are temperature differences throughout. A semiconductor device is said to be out of equilibrium when there is a splitting of the quasi-Fermi levels. etc.

1. What is a non-equilibrium system?
A non-equilibrium system is a physical system that is not in a state of thermodynamic equilibrium, meaning that it is not at a uniform temperature or pressure. Non-equilibrium systems are characterized by the presence of energy or matter flow, which causes changes in the system over time.
2. How are non-equilibrium systems different from equilibrium systems?
Non-equilibrium systems differ from equilibrium systems in that they are constantly changing and do not have a steady state. In contrast, equilibrium systems are stable and do not experience any energy or matter flow. Non-equilibrium systems are also typically more complex and dynamic, while equilibrium systems are simpler and easier to study.
3. What are some examples of non-equilibrium systems?
Examples of non-equilibrium systems include chemical reactions, living organisms, and weather patterns. In chemistry, a reaction system that is not at equilibrium will continue to react until it reaches equilibrium. Similarly, living organisms are constantly taking in and expelling energy and matter, making them non-equilibrium systems. Weather patterns, such as hurricanes and tornadoes, are also examples of non-equilibrium systems due to the constant flow of energy and matter.
4. Why is it important to understand non-equilibrium systems?
Understanding non-equilibrium systems is important for many fields of science, including chemistry, biology, and meteorology. These systems play a crucial role in natural processes and can help us better understand the world around us. Additionally, studying non-equilibrium systems can also lead to advancements in technology and medicine.
5. What are some challenges in studying non-equilibrium systems?
One of the main challenges in studying non-equilibrium systems is their complexity. These systems are often highly dynamic and can be difficult to model and predict. Additionally, non-equilibrium systems can exhibit emergent behavior, meaning that the overall system behavior cannot be predicted from the individual components. This makes it challenging to fully understand and control these systems.
