First theorem of thermodynamics
WebThe first law of thermodynamics is the conservation-of-energy principle stated for a system where heat and work are the methods of transferring … WebThe First Law of Thermodynamics The change in a system’s energy during a thermodynamic process equals the heat added to the system, minus the work it performs on its environment. 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.

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… WebThermodynamics Variables are either extensive or intensive. To illustrate the dif-ference between these kings of variables, think of mass and density. The mass of an object depends on the amount of material in the object, the density does not. Mass is an extensive variable, density is an intensive variable. In thermo-
