Mokslas geriau įsimena, kai apibrėžimas susiejamas su tuo, ką galima išmatuoti ar stebėti.
Mixing two gases usually increases the number of accessible microscopic arrangements and therefore increases entropy.

At constant temperature and pressure, ΔG combines enthalpy and entropy to indicate thermodynamic spontaneity.
Konkretus patikrinimas
Whether a process can be thermodynamically favourable depends on more than heat alone. Gibbs energy combines enthalpy and entropy at a specified temperature.
