Thermodynamics and Energy


Tait, Force and Entropy

Authors: Jeremy Dunning-Davies

Almost 150 years ago, Peter Guthrie Tait gave a lecture to a British Association meeting and took as his subject 'force'. His conclusions were both interesting and controversial but possibly offer a means to understanding better the notion of entropy as it appears in classical thermodynamics. This suggestion, however, applies to entropy - or, more accurately, to entropy difference - as it appears in classical thermodynamics and not to the quantity with the same name which occurs in statistical mechanics and information theory. Finally, there is included a brief examination of the plethora of recent claims to have identified violations of the Second Law of Thermodynamics in nanosized systems. Doubt is cast on the validity of such claims.
