The specific heat capacity of cadmium-doped lead antimony alloy PbSb3 is studied in the cooling mode to compare with the known heat capacity of the reference lead sample. Using the experimentally found values of the cooling rates of samples made of alloys and the standard and knowing the masses, polynomials are plotted to describe the temperature dependence of the heat capacity in the alloys. The polynomials are described by a four-member equation. Integrating over the specific heat capacity, polynomials are obtained for the temperature dependence of changes in enthalpy, entropy and the Gibbs energy for PbSb3. These functions indicate that an increase in temperature results in growing heat capacity, enthalpy, and entropy of alloys, and the value of the Gibbs energy decreases. The increase in cadmium content causes reduction in the heat capacity, heat transfer coefficient, enthalpy, and entropy in PbSb3. [ABSTRACT FROM AUTHOR] |
