Definition of Gibbs free energy in English:

Gibbs free energy

noun

Chemistry

A thermodynamic quantity equal to the enthalpy (of a system or process) minus the product of the entropy and the absolute temperature.
〔化〕吉布斯自由能（符号： G ）
Example sentencesExamples
- The change in Gibbs free energy equals the enthalpy change for the reaction minus the product of the absolute temperature and the change in entropy for the reaction.
- The amount of mechanical work that can be performed in these states is equal to the change in the Gibbs free energy that occurs in them.
- As pressure is a way to modify the Gibbs free energy, pressure allows the exploration of phase transitions and protein substates.
- The sequences of the two proteins vary at only 12 positions, yet only two positions are largely responsible for the observed difference in Gibbs free energy of denaturation.
- In an equilibrium situation (ice and water at 0 degrees Celsius, or salt and a saturated brine) the Gibbs free energy of both components is equal, and nothing (no melting, freezing, dissolving etc.) happens.

Origin

Named after J. W. Gibbs (see Gibbs, Josiah Willard).
