Carbon dioxide is a substance whose properties have been the subject of innumerable investigations. Particularly the pressure-volume-temperature relationships when in the gaseous and liquid phases have provided data for the basis of equations of state. The thermal properties are not so well known and an investigation of these is the purpose of the following paper. The actual measurements to be described deal with the direct determination of the latent heat of fusion, the latent heat of sublimation and the specific heats of the solid and liquid over the temperature range of 0°C. to —184°C. The experimental methods employed are of sufficient interest to warrant a detailed description. Since it was found that the specific heat of the solid carbon dioxide gave abnormally high results the expansion coefficient of the solid was measured.
