Tiede jää mieleen, kun määritelmä yhdistyy johonkin mitattavaan tai havaittavaan.
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.
Konkreettinen tarkistuspiste
Whether a process can be thermodynamically favourable depends on more than heat alone. Gibbs energy combines enthalpy and entropy at a specified temperature.
