👉 Nondissipation is a concept in thermodynamics that describes the behavior of systems under conditions where energy dissipation does not occur. This means that a system's entropy remains constant, even as heat flows from one state to another. In other words, the energy stored in a system is conserved. Nondissipative systems are those that can maintain their internal states without any external influence or change. They are characterized by properties such as temperature, volume, and mass that do not vary with
