Entropy is a scientific concept that is most commonly associated with a state of disorder, randomness, or uncertainty. The term and the concept are used in diverse fields, from classical thermodynamics, where it was first recognized, to the microscopic description of nature in statistical physics, and to the principles of information theory.
The second law of thermodynamics states that the total entropy of a system either increases or remains constant in any spontaneous process; it never decreases. An important implication of this law is that heat transfers energy spontaneously from higher- to lower-temperature objects, but never spontaneously in the reverse direction.
The second law of thermodynamics states that in a reversible process, the entropy of the universe is constant, whereas in an irreversible process, such as the transfer of heat from a hot object to a cold object, the entropy of the universe increases.
La entropía es una función de estado de carácter extensivo y su valor, en un sistema aislado, crece en el transcurso de un proceso que se da de forma natural. La entropía describe lo irreversible de los sistemas termodinámicos. La palabra «entropía» procede del griego (ἐντροπία) y significa evolución o transformación.
1. La entropía se refiere al número de estados que puede tener un sistema. 2. Entre más estados tenga un sistema mayor será su entropía. 3. La entropía se refiere a todos los estados posibles del sistema y no a uno en particular, es decir, se refiere a todos los estados y no a uno en específico. Respuesta. •. Comentar.

29 de may. de 2024 · Entropy, the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. Because work is obtained from ordered molecular motion, entropy is also a measure of the molecular disorder, or randomness, of a system.
The total entropy of a system either increases or remains constant in any process; it never decreases. For example, heat transfer cannot occur spontaneously from cold to hot, because entropy would decrease.
