Some advanced textbooks define entropy by the formula
where the sum runs over all. microstates accessible to the system and P(s) is the probability of the system being in microstate s .
(a) For an isolated system, P(s) = l/ Ω for all accessible states s. Show that in this case the preceding formula reduces to our familiar definition of entropy.
(b) For a system in thermal equilibrium with a reservoir at temperature T, P(s) =. Show that in this case as well, the preceding formula agrees with what we already know about entropy.
