![]() ![]() nd the pressure as a function of V and T. Use the Debye approximation to nd the equation of state of the solid, i.e. The standard molar entropy of Al2O3 Al 2 O 3 is obtained by adding the Debye. The expression for the energy of a solid depends in general on the volume. Once you have obtained a reasonable fit to the heat capacity data, calculate the ‘non-Debye’ contribution to the standard molar entropy by dividing your polynomial function, P(T) P ( T), by T T and integrating the result from the low temperature limit up to 298 K. In this work experimental heat capacities for -Ca 2 SiO 4 and Ca 3 Si 2 O 7 are taken from King 40 and for -Ca 2 SiO 4 and Ca 3 SiO 5 from Todd 42.The data are fitted using the six-parameter-fit provided in Eq. This book is a part of the four-volume series, entitled “A Textbook of Physical Chemistry – Volume I, II, III, IV”. For the temperature much greater than the Debye temperature, we nd using ey1 + y lnZ N kT 3Nln DT+ N E N + 3NkT S Nk 3ln DT+ 4 3. The method is completely general and free of any restrictions on its application to analysis of thermophysical properties of solids from low to melting temperatures. ![]() ![]() ISBN: 8193872010, 9788193872017 (Paperback)īuy: Amazon India / Amazon USA / Amazon UK / Amazon Canada / Amazon France / Amazon Germany / Amazon Italy / Amazon Spain / Amazon Japan / Amazon Brazil / Amazon Australia / Amazon Netherlands / Amazon MexicoĪn advanced-level textbook of physical chemistry for the graduate (B.Sc) and postgraduate (M.Sc) students of Indian and foreign universities. A novel method is introduced to accurately calculate the entropy of solid metals for the first time by using integer and non-integer n-dimensional Debye functions.
