Entropy and Constraint of Motion

Entropy and the Shelf Model: A Quantum Physical Approach to a Physical Property

“…In this case the particles are influenced by stronger forces than in the case of the pure halogens with nonpolar bonds. 6 Since hydrogen atoms have smaller masses than the halogen atoms, the particle mass decreases compared to the respective halogens. Both effects cause the entropy values of the hydrogen halides to be smaller than those of the pure gaseous halogens (Figure 14).…”

“…Former methods of entropy interpretation were rather unconvincing as they tried to understand entropy in terms of order and disorder (3,4). In recent years entropy has been described in connection with particle motion and dispersal of energy (5)(6)(7)(8). But entropy as a physical property, has not yet been discussed.…”

Valid Entropy-Enthalpy Compensation: Its True Physical-Chemical Meaning

“…Interestingly, the above seemingly logically clear standpoint is actually not something completely new, but has apparently gotten lost somehow in the 'physical chemistry developments shuffle' (or likewise) … There was a relatively recent and a really interesting discussion on the closely related theme in the Journal of Chemical Education (see [17][18][19] and the references therein).…”

Give Them Money: The Boltzmann Game, a Classroom or Laboratory Activity Modeling Entropy Changes and the Distribution of Energy in Chemical Systems

“…Recently in this Journal (1)(2)(3)(4)(5)(6)(7)(8)(9)(10) and on the CHEMED-L listserv (11) there has been a lively discussion of the meaning of "entropy" and, in particular, how characterizing it as "disorder" is not helpful. Attempts have been made to characterize entropy qualitatively as the "spreading and sharing of energy" (12) or the "dispersal of energy" (5).…”
