ENTROPY SYNONYM HOW TO
The thermodynamic definition was developed in the early 1850s by Rudolf Clausius and essentially describes how to measure the entropy of an isolated system in thermodynamic equilibrium. There are two related definitions of entropy: the thermodynamic definition and the statistical mechanics definition. Willard Gibbs, Graphical Methods in the Thermodynamics of Fluids

Thermodynamic entropy has the dimension of energy divided by temperature, which has a unit of joules per kelvin (J/K) in the International System of Units. The second law is then a consequence of this definition and the fundamental postulate of statistical mechanics.
This is the basis of the modern microscopic interpretation of entropy in statistical mechanics, where entropy is defined as the amount of additional information needed to specify the exact physical state of a system, given its thermodynamic specification. These processes reduce the state of order of the initial systems, and therefore entropy is an expression of disorder or randomness. It determines that thermal energy always flows spontaneously from regions of higher temperature to regions of lower temperature, in the form of heat. Thus, entropy is also a measure of the tendency of a process, such as a chemical reaction, to be entropically favored, or to proceed in a particular direction. In classical thermodynamics, the concept of entropy is defined phenomenologically by the second law of thermodynamics, which states that the entropy of an isolated system always increases or remains constant. During this work, entropy accumulates in the system, which then dissipates in the form of waste heat. Such devices can only be driven by convertible energy, and have a theoretical maximum efficiency when converting energy to work. Maximum entropy probability distribution Įntropy is a thermodynamic property that can be used to determine the energy not available for work in a thermodynamic process, such as in energy conversion devices, engines, or machines.Entropy (Hip Hop Reconstruction from the Ground Up).
