In thermodynamics, the Onsager reciprocal relations express the equality of certain ratios between flows and forces in thermodynamic systems out of equilibrium, but where a notion of local equilibrium exists. "Reciprocal relations" occur between different pairs of forces and flows in a variety of physical … Ver mais The fundamental equation The basic thermodynamic potential is internal energy. In a simple fluid system, neglecting the effects of viscosity the fundamental thermodynamic equation is written: Ver mais Let $${\displaystyle x_{1},x_{2},\ldots ,x_{n}}$$ denote fluctuations from equilibrium values in several thermodynamic quantities, and let $${\displaystyle S(x_{1},x_{2},\ldots ,x_{n})}$$ be the entropy.
