WebAbstract. A 2 FeCoO 6-δ (A = Ca or Sr) is synthesized by the solid-state synthesis method and their specific heat capacities are evaluated at 40 ˚ C using a heat flow meter. The effect of the A-cation size on the specific heat capacity of these compounds is observed. The specific heat capacity of Sr 2 FeCoO 6-δ is found to be the highest, and that of Ca 2 … WebSep 9, 2024 · 8.1: Heat Capacity. Definition: The heat capacity of a body is the quantity of heat required to raise its temperature by one degree. Its SI unit is J K −1. Definition: The specific heat capacity of a substance is the quantity of heat required to raise the temperature of unit mass of it by one degree. Its SI unit is J kg −1 K −1.

WebApr 9, 2024 · A theory of the specific heat of solids proposed by Albert Einstein in 1906. In this theory, Einstein attributed the specific heat of solids to the vibrations of the solid and made the simplifying assumption that all the vibrations have the same frequency. This theory was partially successful since it was able to derive Dulong and Petit's law ... WebJul 20, 2024 · Solids which contain molecules rather than atoms have much higher heat capacities than 3 R. In addition to the vibration of the whole molecule about its site in the crystal lattice, the individual atoms can also vibrate with respect to each other. shandy dittman
