Heat capacity of liquid mercury between 0-degrees and 450-degrees-C; calculation of certain thermodynamic properties of the saturated liquid and vapor

Abstract

The enthalpy of liquid mercury was measured from 0° to 450° C by the " drop" method. These and other precise published data were used to calculate a number of the rmodynamic properties of liquid and gaseous mercury at the vapor pressures from the triple point ,-38.88°, to + 500° C. The entropy calculated from data on the vapor and liq uid was compared with that derived from published low-temperature heat-capacity data for the solid. The calculated values of vapor pressure, also using data on the vapo r and liquid, were fo und to agree over a wide temperature range with certain published experimental values when independently derived gas-imperfection and published temperature-scal e corrections were applied.
