Mokslas geriau įsimena, kai apibrėžimas susiejamas su tuo, ką galima išmatuoti ar stebėti.
At constant temperature and pressure, ΔG combines enthalpy and entropy to indicate thermodynamic spontaneity.

Chemical reactions rearrange bonds and redistribute energy. If the reacting system transfers energy to its surroundings as heat at constant pressure, its enthalpy change is negative.
