La ciència es recorda millor quan una definició es connecta amb alguna cosa mesurable o observable.
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.
Punt de comprovació
Whether a process can be thermodynamically favourable depends on more than heat alone. Gibbs energy combines enthalpy and entropy at a specified temperature.
