(b)  When left alone, systems tend to undergo spontaneous changes until equilibrium is attained, both internally and with their surroundings.

(c)   Internally reversible processes do not actually occur but serve as hypothetical limiting cases as internal irreversibilities are reduced further and further.

(d)  The energy of an isolated system remains constant, but its entropy can only decrease.

(e)   The maximum coefficient of performance of any refrigeration cycle operating between cold and hot reservoirs at 408F and 808F, respectively, is closely 12.5.
