Dissipation is the result of irreversible processes that take place in inhomogeneous thermodynamic systems. A dissipative process is a process in which energy is transformed from some initial form to some final form; the capacity of the final form to do mechanical work is less than that of the initial form. For example, transfer of energy as heat is dissipative because it is a transfer of internal energy from a hotter body to a colder one. The second law of thermodynamics implies that this reduces the capacity of the combination of the two bodies to do mechanical work. Thermodynamic dissipative processes are essentially irreversible. They produce entropy at a finite rate. In a process in which the temperature is locally continuously defined, the local density of rate of entropy production times local temperature gives the local density of dissipated power. Important examples of irreversible processes are: ⁕Heat flow through a thermal resistance ⁕Fluid flow through a flow resistance ⁕Diffusion ⁕Chemical reactions ⁕Electrical current flow through an electrical resistance. The concept of dissipation was introduced in the field of thermodynamics by William Thomson in 1852.
