Abstract

Abstract In the first part of the paper of which this is an abstract, an account is given of the apparatus and the method employed in determining the atomic heats of the metals Na, Al, Fe, Zn, Ag, Cd, and Pb, at various points in the range from 0° to about – 160°C. A new method of maintaining an enclosure for long periods at any desired temperature within this range is described, the Joule-Thomson cooling effect of air on expansion being utilised for this purpose.
