Abstract:
The enthalpy of liquid copper up to a temperature of $2000$ K is investigated by the drop method with an error from $1$ to $1.5\%$. The measurement results are compared with the literature data. It is shown that the spectral emissivity of copper melt depends on temperature. The obtained data on enthalpy are approximated by an equation. The true heat capacity of liquid copper $c_p=36.33$ J/(mol K), the melting heat $\Delta H=13.59$ kJ/mol, and the melting entropy $\Delta S=10.01$ J/(mol K) of copper are calculated.
