Prigogine called these systems dissipative systems, because they are formed and maintained by the dissipative processes which take place because of the exchange of energy between the system and its environment and because they disappear if that exchange ceases. Chemical Thermodynamics. Such details are often referred to as disorder on a microscopic or molecular scale, and less often as dispersal of energy. (See Constraints below. t If the system contracts, in the present article it is said to do negative work on the surroundings. ): While reversible processes are a useful and convenient theoretical limiting case, all natural processes are irreversible.

The non-equilibrium thermodynamics has been applied for explaining how ordered structures e.g. Waveparticle duality accounts for the probabilistic nature of quantum mechanics and for indeterminacy. The second law of thermodynamics indicates the irreversibility of natural processes, and in many cases, the tendency of natural processes to lead towards spatial homogeneity of matter and energy, especially of temperature.

It makes it possible to study the most varied problems, such as city traffic problems, the stability of insect communities, the development of ordered biological structures and the growth of cancer cells to mention but a few examples. [15][16][17] 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. When two initially isolated systems are combined into a new system, then the total internal energy of the new system, Usystem, will be equal to the sum of the internal energies of the two initial systems, U1 and U2: The First Law encompasses several principles: Combining these principles leads to one traditional statement of the first law of thermodynamics: it is not possible to construct a machine which will perpetually output work without an equal amount of energy input to that machine.
