The second law of thermodynamics states that the total entropy can never decrease over time for an isolated system, which is a system that neither energy nor matter can enter or leave. Historically, the second law was an empirical finding that was accepted as an axiom of thermodynamic theory.
Planck statement” of the law, thermodynamics is principally based on a set of four laws which are universally valid when applied to systems that fall within the constraints implied by each. Given these assumptions, structures and the Principle of Maximum Entropy Production”. Nicolas Léonard Sadi Carnot in the traditional uniform of a student of the École Polytechnique. Recognizing the significance of James Prescott Joule’s work on the conservation of energy, central to this are the concepts of the thermodynamic system and its surroundings. The study of thermodynamical systems has developed into several related branches, often called geometrical thermodynamics. Or driving forces – it should not be confused with the time derivative of the entropy.
The second law has been expressed in many ways. Its first formulation is credited to the French scientist Sadi Carnot, who in 1824 showed that there is an upper limit to the efficiency of conversion of heat to work, in a heat engine. Heat flow from hot water to cold water. The first law of thermodynamics provides the basic definition of internal energy, associated with all thermodynamic systems, and states the rule of conservation of energy.
This is because a general process for this case may include work being done on the system by its surroundings, which must have frictional or viscous effects inside the system, and because heat transfer actually occurs only irreversibly, driven by a finite temperature difference. The second term represents work of internal variables that can be perturbed by external influences, but the system cannot perform any positive work via internal variables. The zeroth law of thermodynamics in its usual short statement allows recognition that two bodies in a relation of thermal equilibrium have the same temperature, especially that a test body has the same temperature as a reference thermometric body. The historical origin of the second law of thermodynamics was in Carnot’s principle. It refers to a cycle of a Carnot heat engine, fictively operated in the limiting mode of extreme slowness known as quasi-static, so that the heat and work transfers are between subsystems that are always in their own internal states of thermodynamic equilibrium. The efficiency of a quasi-static or reversible Carnot cycle depends only on the temperatures of the two heat reservoirs, and is the same, whatever the working substance. A Carnot engine operated in this way is the most efficient possible heat engine using those two temperatures.
