In differential form, this is written (1) d E = d Q − d W where Q represents heat and W represents work. This is just a statement of conservation of energy. rdcc: users wfh rdp6 bb

"In the first half of the eighteenth century, French philosopher and mathematician Émilie du Châtelet made notable contributions to the emerging theoretical framework of energy by proposing a form of the law of conservation of energy that recognized the inclusion of kinetic energy. Empirical developments of the early ideas, in the century following, wrestled with contravening concepts such as the caloric theory of heat. " - First theorem of thermodynamics

WebSep 9, 2024 · 16.2: The Third Law of Thermodynamics. Nernst’s heat theorem and Planck’s extension of it, while originally derived from observing the behaviour of chemical reactions in solids and liquids, is now believed to apply quite generally to any processes, and, in view of that, it is time to reconsider our description of adiabatic demagnetization.

The Onsager reciprocal relations have been considered the fourth law of thermodynamics. They describe the relation between thermodynamic flows and forces in non-equilibrium thermodynamics, under the assumption that thermodynamic variables can be defined locally in a condition of local equilibrium. These relations are derived from statistical mechanics under the principle of microscopic reversibility (in the absence of external magnetic fields). Given a set of extensive pa…
