Abstract

We have determined the heat capacity of cyanogen gas using the adiabatic expansion method of Lummer and Pringsheim. Pure nitrogen was used as the standard comparison gas, its heat capacity being calculated from spectroscopic data. Two different samples of cyanogen were used, each of which was prepared from copper sulphate and potassium cyanide. Care was taken to free the gas from hydrogen cyanide, water, and carbon dioxide. In Table I the experimental molal heat capacities at constant pressure, obtained at three different temperatures, are given. The values of CP0 are those for the gas at infinite attenuation.
