A closed system is a physical system that does not exchange matter with its surroundings but can exchange energy. It is often used in thermodynamics to simplify the analysis of energy transformations by focusing on energy exchanges only.

Exchange energy is a quantum mechanical phenomenon that arises from the exchange interaction between identical particles, leading to a decrease in the system's total energy when particles are indistinguishable. This concept is crucial in understanding the stability of matter, magnetic properties of materials, and the behavior of electrons in atoms and molecules.

Thermodynamics is the branch of physics that deals with the relationships between heat, work, temperature, and energy. It is fundamental in understanding how energy is transferred in physical systems and the limitations of energy conversion processes.
