  • Descrição: The two-phase isochoric heat capacity of nitrogen tetroxide was measured in the temperature range from 261.74 K to the critical temperature (431.072 K) at densities between 201.21 and 1426.5 kg times m super(-3) using a high-temperature and high-pressure adiabatic calorimeter. The measurements were performed in the two-phase region for 26 isochores (15 liquid and 11 vapor densities) including the coexistence curve and critical region. Uncertainties of the measurements are estimated to be 2%. The original temperatures and C sub(V) data were converted to the ITS-90. The liquid and vapor two-phase isochoric heat capacities, temperatures, and densities at saturation were extracted from experimental data for each measured isochore. From measured (T sub(S), p sub(S), C' sub(V2), C double prime sub(V2)) data, the values of second temperature derivatives of vapor-pressure d super(2)/P sub(S)/dT super(2) and chemical potential d super(2) mu /dT super(2) were derived using the Yang-Yang relation. The results were compared with values calculated from other vapor-pressure equations. The values of saturated densities and critical parameters derived in calorimetric experiments were compared with literature data. The unusual temperature behavior of d super(2)P sub(S)/dT super(2) and d super(2) mu /dT super(2) was found at low temperatures around 351 K and near the critical point.
