The entropy of an isolated system not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium. ~ Rudolf Clausius
Clausius quotes by Rudolf Clausius
The algebraic sum of all the transformations occurring in a cyclical process can only be positive, or, as an extreme case, equal to nothing.
[Statement of the second law of thermodynamics, 1862] ~ Rudolf Clausius
Clausius quotes by Rudolf Clausius
It is very desirable to have a word to express the Availability for work of the heat in a given magazine; a term for that possession, the waste of which is called Dissipation. Unfortunately the excellent word Entropy, which Clausius has introduced in this connexion, is applied by him to the negative of the idea we most naturally wish to express. It would only confuse the student if we were to endeavour to invent another term for our purpose. But the necessity for some such term will be obvious from the beautiful examples which follow. And we take the liberty of using the term Entropy in this altered sense ... The entropy of the universe tends continually to zero. ~ Peter Guthrie Tait
Clausius quotes by Peter Guthrie Tait
In despair, I offer your readers their choice of the following definitions of entropy. My authorities are such books and journals as I have by me at the moment.
(a) Entropy is that portion of the intrinsic energy of a system which cannot be converted into work by even a perfect heat engine. - Clausius.
(b) Entropy is that portion of the intrinsic energy which can be converted into work by a perfect engine. - Maxwell, following Tait.
(c) Entropy is that portion of the intrinsic energy which is not converted into work by our imperfect engines. - Swinburne.
(d) Entropy (in a volume of gas) is that which remains constant when heat neither enters nor leaves the gas. - W. Robinson.
(e) Entropy may be called the 'thermal weight', temperature being called the 'thermal height.' - Ibid.
(f) Entropy is one of the factors of heat, temperature being the other. - Engineering.
I set up these bald statement as so many Aunt Sallys, for any one to shy at.
[Lamenting a list of confused interpretations of the meaning of entropy, being hotly debated in journals at the time.] ~ Sydney Herbert Evershed
Clausius quotes by Sydney Herbert Evershed
In all cases where work is produced by heat, a quantity of heat proportional to the work done is expended; and inversely, by the expenditure of a like quantity of work, the same amount of heat may be produced. ~ Rudolf Clausius
Clausius quotes by Rudolf Clausius
Heat can never pass from a colder to a warmer body without some other change, connected therewith, occurring at the same time. ~ Rudolf Clausius
Clausius quotes by Rudolf Clausius
The total energy of the universe is constant; the total entropy is continually increasing. ~ Rudolf Clausius
Clausius quotes by Rudolf Clausius
Clausius and Darwin cannot both be right. ~ Roger Caillois
