Abstract
In the development of thermodynamics, 19th-century scientist Rudolf Clausius devised mathematical equations with which to describe the actions and relationships of heat and work. This paper traces his thinking from his 1850 publication on "The Moving Force of Heat and the Laws Which May Be Deduced Therefrom" to the 1879 English edition of his textbook, The Mechanical Theory of Heat, particularly noting his ideas about parallel concepts of energy and entropy.

H Is for Enthalpy, Thanks to Heike Kamerlingh Onnes and Alfred W. Porter
Irmgard K. HowardJournal of Chemical Education2002 79 (6), 697H Is for Enthalpy, Thanks to Heike Kamerlingh Onnes and Alfred W. Porter
Irmgard K. HowardJournal of Chemical Education2002 79 (6), 697During the 19th century the letter H sometimes represented heat, but the designation of enthalpy was placed into the scientific literature in 1909 by J. P. Dalton and credited by him to Heike Kamerlingh Onnes. In 1922 Alfred W. Porter formally proposed ...
