Part 2 The statistical interpretation of entropy: the statistical approach - a specific example; general ideas and development; the definition of a microstate; temperature and entropy in statistical mechanics;Professor J S DugdaleJ. S. Dugdale
The definition of conversion efficiency based on the first law only may be misleading. The first law, and generally energy conservation cannot identify losses of work, possible improvements in energy converting processes, and the effective use of resources. One of the examples is the adiabatic ...
The German physicist Rudolf Clausius originated the concept as "energy gone to waste" in the early 1850s, and its definition went through a number of more precise definitions over the next 15 years. Wikipedia has an interesting "history of entropy" page. ...
[39] thermodynamically analyzed entransy with respect to entropy and concluded that firstly, the entransy have got some difficulties in its definition. It has actually been introduced in the literature following different approaches. The first was based on a cycle and the other one on heat exchange...

Note 1. If incomplete systems are permitted (0<∑k=1npk≤1) then the definition Hn(p1,…,pn)=−∑k=1npklog2pk∑k=1npk is used. Here n = 1 is also permissible and gives as entropy of a single event H1(p1)=−logp1(p1>0). We take here the following ‘reasonable’ propertie...
