Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
A thermodynamic quantity equal to the enthalpy (of a system or process) minus the product of the entropy and the absolute temperature.
- ‘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.’
- ‘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.’
- ‘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.’
Named after J. W. Gibbs(see Gibbs, Josiah Willard).
