SUMMARY
The specific heat capacity of most solids is approximately 25 J K-1 mol-1, primarily due to the principles outlined in the Dulong-Petit Law, which states that the classical limit of a crystal's heat capacity is 3R per mole. This value reflects the average energy required to raise the temperature of a mole of solid material by one degree Kelvin. Variations exist among different materials, as evidenced by the significant differences in specific heat capacities between substances like glass and copper.
