Heat capacity and thermodynamic functions of alloys of the Pb–Zn system

Abstract

In the “cooling” mode, by comparing the cooling curves of the standard (Pb grade C00) and the samples under study, the effect of lead alloying with zinc additions on the heat capacity and thermodynamic functions of alloys was studied. The calculations were carried out using computer technology and the Sigma Plot program. The performed studies have shown that with increasing temperature and the amount of zinc, the heat capacity, heat transfer coefficient, enthalpy and entropy of alloys increase, while the Gibbs energy value decreases
