Removing Heat and Conceptual Loops from the Definition of Entropy

  title={Removing Heat and Conceptual Loops from the Definition of Entropy},
  author={E. Zanchini and G. Beretta},
  journal={International Journal of Thermodynamics},
A rigorous and general logical scheme is presented, which provides an operative non-statistical definition of entropy valid also in the nonequilibrium domain and free of the usual conceptual loops and unnecessary assumptions that restrict the traditional definition of entropy to the equilibrium domain. The scheme is based on carefully worded operative definitions for all the fundamental concepts employed, including those of system, state of a system, isolated system, separable system, systems… Expand
New definitions of thermodynamic temperature and entropy not based on the concepts of heat and thermal reservoir
From a new rigorous formulation of the general axiomatic foundations of thermodynamics we derive an operational definition of entropy that responds to the emergent need in many technologicalExpand
Recent Progress in the Definition of Thermodynamic Entropy
The principal methods for the definition of thermodynamic entropy are discussed with special reference to those developed by Carath\'eodory, the Keenan School, Lieb and Yngvason, and the presentExpand

Maximum entropy production principle in physics , chemistry and biology
The tendency of the entropy to a maximum as an isolated system is relaxed to the equilibrium (the second law of thermodynamics) has been known since the mid-19th century. However, independentExpand

It is shown that diffusion processes that occur far away from equilibrium can be viewed as at local equilibrium in a space that includes all the relevant variables in addition to the spatial coordinate and the difficulties and ambiguities associated with the lack of a thermodynamic description disappear.

It is shown that, within a quantum mechanical framework, all phenomena which leave a trail of information behind are those where entropy necessarily increases or remains constant, and physics cannot study those processes where entropy has decreased, even if they were commonplace. Expand
