Entropy, the magic ruler?

David Van Den Eindea)

1284 170th St., Bejou, Minnesota 56516, USA

 

The 18th century foundations of the second law of thermodynamics are discussed. The association between Carnot efficiency and Clausius entropy is described to show the questionable use of Clausius entropy as proof of Carnot’s assumption that the rate the ideal gas can convert heat energy to work between temperatures T1 and T2 sets a universal limit on the convertibility of heat to work by all 2T cyclical process.

 

Les fondements du 18e siècle de la deuxième loi de la thermodynamique sont discutés. L'association entre le rendement de Carnot et l'entropie de Clausius est décrite pour montrer l'utilisation discutable de l'entropie de Clausius comme preuve que l'hypothèse de Carnot selon laquelle le taux avec lequel le gaz idéal peut convertir l'énergie thermique en travail entre les températures T1 et T2 fixe une limite universelle à la convertibilité de la chaleur en travail par tous les processus cycliques 2T.

 

Key words: Carnot Cycle; Clausius Entropy; Kinetic Energy; Heat Death of Universe.
