Abstract: A calorimeter includes an adiabatic enclosure surrounding a tube for supporting a sample. In the enclosure is a control chamber in thermal contact with the sample-carrier tube and containing a substantially perfect gas. The temperature of the sample is kept constant during a change of state by varying the pressure of this gas. A differential gas thermometer provides an indication of the difference between the temperature of the sample and that of a thermally insulated reference body which is initially at the same temperature as the sample. An automatic control system varies the pressure of the gas in the control chamber in the sense which tends to cancel any temperature variations detected by the differential gas thermometer. The gas pressure is varied by means of a vertical passage which has its upper end connected to the control chamber and its lower end connected to receive hydraulic liquid from a volumetric pump actuated by the control system.
