Adaptation of the Gibbs reflective model. Learning researcher Graham Gibbs discussed the use of structured debriefing to facilitate the reflection involved in Kolb's experiential learning cycle. Gibbs presents the stages of a full structured debriefing as follows: [24] [a] (Initial experience) Description "What happened?
Gibbs's Equilibrium paper is considered one of the greatest achievements in physical science in the 19th century and one of the foundations of the science of physical chemistry. [2] In these papers Gibbs applied thermodynamics to the interpretation of physicochemical phenomena and showed the explanation and interrelationship of what had been ...
In thermodynamics, the phase rule is a general principle governing multi-component, multi-phase systems in thermodynamic equilibrium.For a system without chemical reactions, it relates the number of freely varying intensive properties (F) to the number of components (C), the number of phases (P), and number of ways of performing work on the system (N): [1] [2] [3]: 123–125
In 1933 (based on work first published in 1910), John Dewey described five phases or aspects of reflective thought: In between, as states of thinking, are (1) suggestions, in which the mind leaps forward to a possible solution; (2) an intellectualization of the difficulty or perplexity that has been felt (directly experienced) into a problem to be solved, a question for which the answer must ...
The theorem is Gibbs's phase rule, not Gibbs' phase rule. (In English, one leaves off the final s only when it's difficult to pronounce.) Gibb's phase rule first appeared in the Transactions of the Connecticut Academy of Sciences in the paper 'On the Equilibrium of . Heterogeneous Substances', published in parts between 1875 & 1878.
The Margules activity model is a simple thermodynamic model for the excess Gibbs free energy of a liquid mixture introduced in 1895 by Max Margules. [1] [2] After Lewis had introduced the concept of the activity coefficient, the model could be used to derive an expression for the activity coefficients of a compound i in a liquid, a measure for the deviation from ideal solubility, also known as ...
A Gibbs measure in a system with local (finite-range) interactions maximizes the entropy density for a given expected energy density; or, equivalently, it minimizes the free energy density. The Gibbs measure of an infinite system is not necessarily unique, in contrast to the canonical ensemble of a finite system, which is unique.
where ln denotes the natural logarithm, is the thermodynamic equilibrium constant, and R is the ideal gas constant.This equation is exact at any one temperature and all pressures, derived from the requirement that the Gibbs free energy of reaction be stationary in a state of chemical equilibrium.
