Tiede jää mieleen, kun määritelmä yhdistyy johonkin mitattavaan tai havaittavaan.

3

Mixing two gases usually increases the number of accessible microscopic arrangements and therefore increases entropy.

5

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.
