Summary
It is shown that, while links exist between the second and third laws, between the zeroth and proposed fourther laws and between the zeroth and second laws, no equivalences have been proved. Moreover, for positive absolute temperatures, the second law is seen to imply the zeroth law, provided the validity of the first law is assumed. However, since this result does not hold for negative absolute temperatures, no redundancy among the laws of thermodynamics can be claimed to have been established.
Riassunto
Si mostra che, mentre esistono legami tra la seconda e la terza legge, tra la legge zero e la quarta e tra la zero e la seconda non sono state provate equivalenze. In più, per temperature assolute positive, si vede che la seconda legge implica la legge zero, restando ferma la validità della prima legge. Comunque, poiché questo risultato non è valido per temperature assolute negative, non si può pretendere di stabilire alcuna ridondanza tra le leggi della termodinamica.
