The efficiency () with which heat energy can be transformed to work is equal to {1 – (T0 / TH)}, which is always less than 100%, even in a slowly transforming reversible process, because, when flowing down a thermal gradient with concomitant cooling, a part of it (= Q0) cannot produce any work when it reaches equilibrium with the surrounding air at T0.	cache/ees-914.pdf	txt/ees-914.txt
