Enthalpy and heat capacity of liquid rubidium within the temperature range of $480$–$1000$ K

Liquid rubidium enthalpy increment was measured by drop method within the temperature range of $480$–$1000$ K. The approximation equation was obtained and the isobaric heat capacity was determined. The estimated errors of the data on the enthalpy and the heat capacity were equal to $0.5\%$ and $1.5\%$, respectively. The results obtained were compared with the available literature data. The position $(723$ K$)$ of the minimum of the liquid rubidium heat capacity was refined. The tables of the recommended values of the caloric properties within the studied temperature range were developed.
