Equilibrium vs. non-equilibrium systems

Equilibrium systems are stable states where conditions remain constant over time unless disturbed, like a balanced scale with equal weights. In these systems, processes occur at equal rates, maintaining stability. Non-equilibrium systems are dynamic and constantly changing, with ongoing processes that prevent a stable state, such as a flowing river or a living organism. They require continuous energy input to maintain their state. In essence, equilibrium systems are static or balanced, while non-equilibrium systems are active and dynamic, continually evolving due to ongoing processes.
