Definition
A state of balance in a closed system where the Gibbs free energy is at its lowest possible value, indicating stability, and is characterized by the equation dG=0, where G is the Gibbs free energy, H is the enthalpy, T is the temperature, and S is the entropy of the system
Summary
Thermodynamic equilibrium is a fundamental concept in physics that describes a state where a system's properties remain constant over time. This state can be categorized into thermal, mechanical, and chemical equilibrium, each playing a crucial role in understanding energy transfer and reactions in various systems. Recognizing these types helps in analyzing real-world applications, such as refrigeration and chemical processes. Understanding thermodynamic equilibrium is essential for students as it lays the groundwork for more advanced topics in thermodynamics and physical chemistry. By grasping the principles of equilibrium, learners can better appreciate how energy systems operate and how they can be manipulated in practical applications, leading to innovations in technology and industry.
