![]() ![]() ![]() When we relate pressure then, to entropy, with #S = S(T,P)#:įor an ideal monatomic gas, #PV = nRT#, so: Which is what you would get for the Maxwell relation. Thus, utilizing this relationship and invoking the Product Rule on #d(PV)#, we get: #w_"rev" = -PdV#.Īnother relationship that relates with heat flow is the one for entropy and reversible heat flow: #q_"rev"# and #w_"rev"# are the most efficient (reversible) heat flow and work, respectively.#\mathbf(DeltaH = DeltaU + Delta(PV)) = q_"rev" + w_"rev" + Delta(PV)# Starting from the first law of thermodynamics and the relationship of enthalpy #H# to internal energy #U#: ![]()
