✦ Synopsis

41o U.S. BUREAU OF STANDARDS NOTES. [J. F. i° LATENT HEAT OF VAPORIZATION OF AMMONIA¢ [A~STRaCT.

] This paper gives detailed description of the calorimeter designed to determine the latent heat of vaporization of ammonia. This important refrigeration constant was determined through the temperature interval -42 ° to +52 ° C. At o ° the latent heat is 3Ol.8 calories per gramme. The results of 34 separate determinations agree with the mean within one part in one thousand.
