State function of a system is in thermodynamics any function that does not depend on the processes undergone by the system but only on the present state. In addition to internal energy are state functions enthalpy H, entropy S, isochoric-isothermic potential F, isobaric-isothermic potential...

While refreshing some thermodynamics for a personal interest in renewable energies, I drafted a reasoning that apparently leads from the 1st law to the 2nd law of thermodynamics, so that the latter, at least for ideal gases undergoing reversible processess, would seem to be just a consequence of...
