Applications of the First Law of Thermodynamics

This lecture covers the concept of molar specific heat for gases and solids, explaining how it differs from liquids. It delves into the definitions of specific heat at constant volume (CV) and constant pressure (CP), exploring the numerical values for various substances. The instructor also discusses the relationship between CV and CP, highlighting the significance of these values in understanding the behavior of ideal gases. Furthermore, the lecture touches upon the principles of equipartition of energy and kinetic theory to explain the specific heat capacities of monoatomic and diatomic gases. The discussion extends to the complexities observed in the specific heat of diatomic gases at different temperature ranges, providing insights into the behavior of solids at low temperatures.
