Teadus jääb meelde, kui definitsioon seotakse millegi mõõdetava või vaadeldavaga.
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.
Konkreetne kontrollpunkt
Whether a process can be thermodynamically favourable depends on more than heat alone. Gibbs energy combines enthalpy and entropy at a specified temperature.
