TL;DR: Results which were obtained in the saturated liquid region (Cv(2) and Cσ) demonstrate the internal consistency of the Cv (ρ,T) data and also show satisfactory agreement with published heat capacity data.
Abstract: Molar heat capacities at constant volume (Cv ,) for nitrogen have been measured with an automated adiabatic calorimeter. The temperatures ranged from 65 to 300 K, while pressures were as high as 35 MPa. Calorimetric data were obtained for a total of 276 state conditions on 14 isochores. Extensive results which were obtained in the saturated liquid region (Cv(2) and Cσ ) demonstrate the internal consistency of the Cv (ρ,T) data and also show satisfactory agreement with published heat capacity data. The overall uncertainty of the Cv values ranges from 2% in the vapor to 0.5% in the liquid.

TL;DR: In this article, a plate-like multilayered system is used to calculate the phase and amplitude of the temperature wave transmitted through a sample for simultaneous determination of the sample's heat capacity and thermal conductivity.

TL;DR: In this article, the authors used a mathematical model for the ignition of thermally thin thermoplastics to evaluate the critical heat flux, and the corresponding critical surface temperature, required for piloted ignition by using the concept that a sample ignites when the mass flux of fuel from the solid into the gas phase reaches a critical value.

TL;DR: In this paper, heat capacity measurements of BaThO3 and BaCeO3 were carried out using differential scanning calorimetry in the temperature range 320-820 K. From the heat capacity values, other thermodynamic functions such as enthalpy increments, entropies and Gibbs energy functions of these compounds were derived.
