RAMSAY, WILLIAM & JOHN SHIELDS. - MOLECULAR SURFACE ENERGY SHOWN.

The Variation of Molecular Surface-Energy with Temperature. Received March 14, - Read March 23, 1893.

(London, Harrison and Sons, 1894). 4to. No wrappers as extracted from "Philosophical Transactions", 1893, Vol. 184. Pp. 647-673 a. 2 plates.

First appearance of an importent paper in the history of physical chemistry in which the authors for the first time shows experimentally that "the molecular surface energy decreases linearly with the temperature, and that the temperature coefficient of molecular surface energy is a colligative property. Determination of the temperature coefficient of molecular surface energy, therefore, were largely employed for the purpose of calculating the molecular weights, and therefrom the molecular complexity, of substances in the liquid state."(Findley "A Hundred years of Chemistry", p. 79).
