Molar Heat Capacity (C(v)) for Saturated and Compressed Liquid and Vapor Nitrogen from 65 to 300 K at Pressures to 35 MPa

Molar heat capacities at constant volume (C(v),) 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 r...

description Molar heat capacities at constant volume (C(v),) 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 (C(v)((2)) and C(σ)) demonstrate the internal consistency of the C(v) (ρ,T) data and also show satisfactory agreement with published heat capacity data. The overall uncertainty of the C(v) values ranges from 2% in the vapor to 0.5% in the liquid.
