Η επιστήμη μένει στη μνήμη όταν ένας ορισμός συνδέεται με κάτι μετρήσιμο ή παρατηρήσιμο.

3

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.

Συγκεκριμένο σημείο ελέγχου

Whether a process can be thermodynamically favourable depends on more than heat alone. Gibbs energy combines enthalpy and entropy at a specified temperature.
