Entropy

The entropy is defined as a measure of thermodynamics, which represents the fraction of energy in a system that is unavailable to perform or carry out a specific job. Also defined as a measure of order or restrictions on carrying out work

Entropy arose in the first instance in the field of physics, but today is applicable to many other areas, such as administration and economics. The latter in the sense of a flow of energy, entropy being a negative energy that hinders the execution of work, the entropy in a system is the tendency to disorder or disorganization own work. In contrast to entropy, entropy is referred to the positive energy of the system, i.e. gives more fluid surrounding energies.

This concept considers the scientific community relatively recently. It was introduced by French engineer RJ Clausius the mid-nineteenth century. It was based on the second law of thermodynamics to develop the concept of entropy, there is no process whose sole result is the transfer of heat from a cold body to another of higher temperature.

The second law of thermodynamics states the entropy growth, i.e., the highest probability of the systems is their progressive disorganization and finally homogenization with the environment. Closed systems are hopelessly doomed to disorganization. However there are systems that, at least temporarily, reversed this trend by increasing their states of organization.

Order and Disorder

Established by the Clausius Second Law, which states that all natural processes cause an increase in the entropy of the universe is of physico-chemical processes. These include chemical reactions, the transfer of heat and matter, diffusion and the like. All these processes increase the entropy and can; unlike for example the motion of a pendulum cannot be idealized as reversible changes. Every chemical reaction marks a difference between past and future; they progress toward a state of equilibrium, which is in our future. Even the compensation of temperature variations in a closed system leads to a uniformity that is in our future. Development here means only so that it leads to the disappearance of their own events.

How do we define stationary states? Any temporal change in entropy can be decomposed into two types of contributions: the "entropy", which is based on the exchange of the system with its environment, and the "entropy" resulting from the irreversible processes within the system. The second law postulates that the entropy is positive ...
