Abstract
A new model of heat capacity is established for solid and liquid materials in the wide temperature range recently, and shows that heat capacity is also dependent on thermal expansion or volume. In this study, we further analyzed the physical meaning of the parameters in the model, and perfected the heat capacity model. The calculated heat capacity in the perfected model is well in accord with the experimental results. And a universal volume-energy relation in materials is predicted by the model, and has important theoretical value.
期刊介绍：
The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems.
Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal:
Low-dimensional systems
Exotic states of quantum electron matter including topological phases
Energy conversion and storage
Interfaces, nanoparticles and catalysts.
